Latest / Stuff You Should Know / Bioluminescence: A Bright and Shiny Fish
Transcript
- 0:00Speaker 1: Brought to you by the reinvented two thousand twelve camera.
- 0:03Speaker 1: It's ready. Are you welcome to Stuff you Should Know?
- 0:08Speaker 1: From House Stuff Works dot Com? Hey, and welcome to
- 0:16Speaker 1: the podcast. I'm Josh Clark. There's Charles W. Chuff Bryant
- 0:20Speaker 1: and uh. You put us together and you get a
- 0:24Speaker 1: little something called Stuff you Should Know. And that's what
- 0:26Speaker 1: this is. Whether you like it or not, you have
- 0:29Speaker 1: to listen to it. It's try. Um. Actually, no one
- 0:32Speaker 1: has to listen to this. It's part of both Obama's
- 0:37Speaker 1: and Romney's platforms. Yeah, it's a part of Obamacare. You
- 0:42Speaker 1: gotta listen to Stuff you Should Know, and you gotta
- 0:44Speaker 1: get an r f D chip in your hand, and
- 0:46Speaker 1: you have to give poor people all your money. None
- 0:49Speaker 1: of that is true, that you have to listen to
- 0:51Speaker 1: the podcast and the porpulal part um. Chuck, how's it going?
- 0:56Speaker 1: It's great. Are you feeling sick? Do you need any
- 0:59Speaker 1: kind of here Obama or otherwise? Now? Are you feeling sick?
- 1:02Speaker 1: I'm fine. Chance, like my shoulder muscles are gonna pop
- 1:06Speaker 1: right out of my skin. I went to that foot
- 1:08Speaker 1: massage play some Buford Highway the other day. You ever
- 1:10Speaker 1: been there. M hm. Treat your feet Is that what
- 1:15Speaker 1: it's called. Yeah, that's a great name. They'll they'll do
- 1:17Speaker 1: an hour on your feet for bucks if that's what
- 1:20Speaker 1: you desire. Oh yeah, I know. About a little bit
- 1:23Speaker 1: bit into it, they'll ask you like, would you want
- 1:25Speaker 1: to go half and half, like half body half foot,
- 1:27Speaker 1: because basically they get you in there, they're going at
- 1:30Speaker 1: your feet and you're like, you know, I don't know
- 1:32Speaker 1: if I could do an hour on my feet. Each
- 1:34Speaker 1: toe has gotten their own massage at this point, like
- 1:37Speaker 1: they're just jelly cracked your toes. Yeah, so they think, yeah,
- 1:40Speaker 1: you know, i'll pay another twenty bucks for the body,
- 1:42Speaker 1: right they give you t it's really nice. You should go.
- 1:45Speaker 1: It does sound nice, but it's not like private. Like
- 1:47Speaker 1: you're in a big room with like fifteen recliners. Everyone's
- 1:50Speaker 1: just sitting around and well we've gotten backrubs at the
- 1:52Speaker 1: mall before. Yeah, that's true. You remember, I don't know
- 1:55Speaker 1: how I got on this Treat your feet Buford Highway.
- 1:58Speaker 1: Go eat some fun and then go get your foot massage.
- 2:01Speaker 1: Where's good fun around here? We're trying to figure that out.
- 2:03Speaker 1: The Yeah, where uh if you are we going to
- 2:09Speaker 1: do this now. Okay, I like fun number two, um,
- 2:14Speaker 1: which is past Claremont. Um, it's in a little shopping center.
- 2:21Speaker 1: Just look it up, okay, I mean it's it's all good,
- 2:23Speaker 1: all good fun. Um. Yeah. I don't know how we
- 2:26Speaker 1: got on there, but some places on Beaureford Highway. Oh
- 2:30Speaker 1: you use some money, seriously, at least some free fun. Um.
- 2:34Speaker 1: This has nothing to do with bioluminescence. No, it doesn't.
- 2:37Speaker 1: Although sometimes if you stir your funt around, chuck, you're
- 2:42Speaker 1: gonna see some um fungus possibly rise to the top
- 2:48Speaker 1: a couple of times. Right, Yeah, that's a good one too.
- 2:51Speaker 1: And um, where those things still alive and not cooked,
- 2:55Speaker 1: they possibly might glow. And where they to glow, you
- 3:00Speaker 1: would say, look at those things, they're bioluminescing. That's right,
- 3:05Speaker 1: because that's what they do. It is a life form
- 3:08Speaker 1: that generates their own glow inside their body, their own life. Yeah,
- 3:12Speaker 1: pretty awesome. And um, you I read a different um
- 3:18Speaker 1: study It was like, what what's the deal with this?
- 3:21Speaker 1: Because this is still very much a mystery. Um, we
- 3:24Speaker 1: have an idea of how this goes down, but not
- 3:28Speaker 1: in every case. We also don't understand why in a
- 3:32Speaker 1: lot of cases, um, and in in some cases we
- 3:35Speaker 1: don't understand how. And the thing is is, I don't
- 3:39Speaker 1: think it's that it's out of the grasp of science
- 3:42Speaker 1: to understand it. I think that when researchers are looking
- 3:45Speaker 1: into this, they just they become so transfixed on the
- 3:48Speaker 1: beautiful glow that they forget what they're doing and waste
- 3:50Speaker 1: tons of time. And then all of a sudden, you're like, oh,
- 3:53Speaker 1: I gotta publish our Paris. And then it's just like
- 3:56Speaker 1: they just write why on a piece of paper and
- 3:59Speaker 1: send it in, as Tracy Wilson of Pop Stuff Great
- 4:03Speaker 1: Podcast points out, and Tracy's articles are always awesome. Yeah,
- 4:06Speaker 1: oh man, they're comprehensive. You know, I never have to
- 4:08Speaker 1: worry about it. Um. Sadly, sometimes scientists can either harm
- 4:15Speaker 1: the light making magic when they try to study them,
- 4:18Speaker 1: this makes it hard to study, or the animal will
- 4:21Speaker 1: exhaust it's light making glow capabilities out of like fear
- 4:26Speaker 1: or defense or spite or spite, which will also make
- 4:30Speaker 1: it hard to study. So those are a couple of reasons,
- 4:32Speaker 1: and the whole just why right. So, Um, we do
- 4:38Speaker 1: have a pretty good handle to some extent, But let's
- 4:42Speaker 1: talk about what luminescence itself is right with that this
- 4:47Speaker 1: light bulb right here in this a key of brand
- 4:50Speaker 1: lamp um. It's incandescent. It's an incandescent light bulb. I
- 4:55Speaker 1: think this is an edison bulb is oh? Is it
- 4:59Speaker 1: like the real old amy looking one sort of um?
- 5:02Speaker 1: So that is pretty simple. It has electricity that passes
- 5:07Speaker 1: through a filment, just a thin metal piece of something metal,
- 5:13Speaker 1: and that heats up, and it heats up so much
- 5:16Speaker 1: that it gives off light, which is incredibly inefficient. And
- 5:20Speaker 1: if say a jellyfish for to do this, it would
- 5:22Speaker 1: catch fire even though it's under water. Right, So what
- 5:27Speaker 1: um living organisms do when they want to give off
- 5:30Speaker 1: light is something called cold light or bioluminescence, which is
- 5:35Speaker 1: the combination of chemicals that produce light like a glow stick,
- 5:40Speaker 1: but no heat. But it is just like a glow stick.
- 5:42Speaker 1: You're combining two things that will make a glow exactly,
- 5:45Speaker 1: except you don't have to shake up the jellyfish. They
- 5:51Speaker 1: do not like that. Or it's like the glow sticks
- 5:53Speaker 1: that I used to sell very often at Stone Mountain
- 5:56Speaker 1: Laser Show. It's like the glows free Summer that I
- 5:59Speaker 1: used to dance with at races. You were at raves
- 6:03Speaker 1: and I was selling these things during like Lee Greenwoods,
- 6:08Speaker 1: Lee Greenwood, Lee Green Would you Proud to be an American? Yeah? Boy,
- 6:11Speaker 1: I heard that song five thousand times. So bad. Anyone
- 6:15Speaker 1: who's never been to a Stone Mountain, Georgia. They have
- 6:18Speaker 1: a big rock there and they have a laser show
- 6:20Speaker 1: on it during the summer. It's a big rock that
- 6:22Speaker 1: has a basically the Confederate heroes carved into the side
- 6:26Speaker 1: of it by the guy who did Mount Rushmore. How's
- 6:29Speaker 1: that the same guy? Huh? Yeah, And they show a
- 6:31Speaker 1: very corny laser show every summer since like the early
- 6:35Speaker 1: nineteen eighties, and not just once this summer, like every
- 6:38Speaker 1: night during the summer. Yeah, that's why I've heard it
- 6:40Speaker 1: ten thousand times. It's something And Chuck, you still work there.
- 6:42Speaker 1: I think you left that out selling gloves sticks sticks
- 6:46Speaker 1: full circle. Yes, all right, let's quit stalling. Let's talk
- 6:49Speaker 1: about bioluminescence. Okay, that's all over the place. Uh. Like
- 6:53Speaker 1: you said, we don't know exactly how it works in
- 6:55Speaker 1: all cases, but we do know that these animals do
- 6:59Speaker 1: mix together. There are different substances, just like a glow stick,
- 7:01Speaker 1: wood and to turn their little glow on and off. Um.
- 7:08Speaker 1: Here on the planet, not in the ocean, because that's
- 7:11Speaker 1: where most of the stuff takes place here on planet Earth.
- 7:13Speaker 1: On the dry land. Uh, you can have things glowing
- 7:17Speaker 1: like fox fire, which is this fungus that feeds on
- 7:21Speaker 1: rotting wood. You look at pictures of fox fire. Pretty cool. Yeah,
- 7:24Speaker 1: doesn't look real, but it's real. It's very real. Um.
- 7:27Speaker 1: The jack O lander mushroom you can google that as well.
- 7:30Speaker 1: That's my favorite bioluminous in organism. Why just because it's
- 7:34Speaker 1: the South on land on Terra Firma, because it's a
- 7:37Speaker 1: perfectly named thing, the jack O lantern mushroom. Like it
- 7:41Speaker 1: has that glow coming through the gills, um, and just
- 7:44Speaker 1: the gills, so it looks like there's like this glow
- 7:47Speaker 1: coming inside and there's like holes where it's coming out of.
- 7:50Speaker 1: It's so neat. My favorite on Terra Firma is the
- 7:54Speaker 1: lightning bug a k a. The firefly. Here in the
- 7:57Speaker 1: South and I guess I'm not sure where else it
- 7:59Speaker 1: on lightning bugs, but definitely in the Sound. You'll see
- 8:03Speaker 1: them come out every summer and if you're a little kid,
- 8:05Speaker 1: you can go around and catch them. And put them
- 8:08Speaker 1: in a jar and then and then release them. And
- 8:11Speaker 1: in fact you may be harming them just by catching them.
- 8:13Speaker 1: But what you don't want to do if you're a
- 8:15Speaker 1: kid is like smash these things because it's just yeah,
- 8:20Speaker 1: that means you're gonna end up being a serial killer
- 8:22Speaker 1: one day probably. Uh. So the firefly is uh, you
- 8:29Speaker 1: know you generally you think of them as the adults
- 8:31Speaker 1: lying around, but their little larva can glow as well
- 8:33Speaker 1: on the ground, right, And a lot of people call
- 8:36Speaker 1: um firefly lava glow worms, but glow worms are apparently
- 8:40Speaker 1: another kind of fly larvae. Fireflies are fireflies or lightning bugs.
- 8:44Speaker 1: That's right, um, centipedes, millipedes, there's all all kinds of
- 8:48Speaker 1: little things that can glow worms. Uh, there's some worms
- 8:52Speaker 1: that give off a bioluminescent sludge and no one has
- 8:56Speaker 1: any idea why is it their poop and then pop it?
- 8:59Speaker 1: I don't think so. Ober. The the the secretion they
- 9:04Speaker 1: produce when they're mating and all that, it's probably like that.
- 9:08Speaker 1: It probably comes from the ring. I can't remember the
- 9:10Speaker 1: name of the ring. So that's on Earth. But if
- 9:12Speaker 1: you really want to get down to some cool, glowing creatures.
- 9:16Speaker 1: You need to dive down into the ocean to the
- 9:19Speaker 1: twilight zone, which I think we've talked about that, haven't
- 9:22Speaker 1: we know? We talked about it in biospeleiol in caves. Yeah,
- 9:26Speaker 1: there's different zones of light penetration in caves and in
- 9:29Speaker 1: the ocean too, that's right. Um, the twilight zone is
- 9:33Speaker 1: generally about six hundred sixty two feet deep. Six It
- 9:40Speaker 1: depends because obviously different kinds of ocean water are gonna
- 9:44Speaker 1: allow different amounts of light in. It depends on what
- 9:46Speaker 1: the ocean floor looks like, but it is, um, it
- 9:50Speaker 1: is the dysphotic or poorly lit zone deeper than the
- 9:54Speaker 1: euphotic sunlit zone or good zone or shout or then
- 10:01Speaker 1: the aphotic midnight zone, which is like scary no light.
- 10:05Speaker 1: That's a scary time down there, right. Those are the
- 10:08Speaker 1: things down there that have like no eyes, right, because
- 10:12Speaker 1: there's no reason, same like with the caves. So um, yeah,
- 10:16Speaker 1: I remember what was the Prometheus Salaman just three ft
- 10:20Speaker 1: long and doesn't have eyes. The scariest thing ever except
- 10:23Speaker 1: for the cigar shark, which will actually get do in here. Okay,
- 10:26Speaker 1: so is that the cookie cutter shark man that things
- 10:29Speaker 1: frightening um. So in this uh, this twilight zone, the
- 10:34Speaker 1: desphotic zone or mezo pelagic zone, mesopelagic zone, stop laughing
- 10:41Speaker 1: at me. Uh there, this is where most of the
- 10:44Speaker 1: bioluminescent organisms on Earth can be found. And the light
- 10:48Speaker 1: that penetrates this area um is a blue green color
- 10:53Speaker 1: because the red, yellow, orange. Yeah, the red, yellow and
- 10:58Speaker 1: orange are absorbed by the seawater above and the violet
- 11:01Speaker 1: is scattered, so the blue and the green are the
- 11:03Speaker 1: ones that get through. So everything's just kind of color
- 11:06Speaker 1: blue green. That's what the sunlight is. So most of
- 11:09Speaker 1: the bioluminescent organisms in this um dysphotic zone, dysphotic zone
- 11:14Speaker 1: have evolved to produce light at that same wavelength from
- 11:20Speaker 1: something like four four hundred seventy nanometers, which is like
- 11:23Speaker 1: the blue green spectrum. That's right, So matches that sunlight, yeah,
- 11:28Speaker 1: which is pretty cool. Yeah, well we'll get to it.
- 11:30Speaker 1: But it can lead to some cool things like camouflage.
- 11:34Speaker 1: So uh, the but it also means that it travels farther.
- 11:38Speaker 1: Light travels that that type of light travels the farthest
- 11:41Speaker 1: and water because it has a shorter wavelength than the
- 11:43Speaker 1: other types. So an animal producing this could really cook
- 11:49Speaker 1: down there basically. Yeah. Uh, we're talking jellyfish, shrimp, grill, squid,
- 11:56Speaker 1: other kinds of fish, marine worms, whatever the heck that
- 11:58Speaker 1: is therely what you think it is. Yeah, what are
- 12:02Speaker 1: those one worms called? It like come up out of
- 12:04Speaker 1: the little tubes tube worms? Oh yeah, yeah, I believe
- 12:09Speaker 1: that's what they're called. Um, either that or it just
- 12:12Speaker 1: made some terrible like sixth grade joke. But um. They
- 12:16Speaker 1: they they are like on the ocean bottom and they
- 12:20Speaker 1: they have they just come out of these tubes and
- 12:24Speaker 1: grab stuff and go back in there like three ft long.
- 12:28Speaker 1: You've not seen this sea snake to me. Yeah, but
- 12:31Speaker 1: they're I think they're attached or they may be attached
- 12:34Speaker 1: to their tubes, or they just never come all the
- 12:38Speaker 1: way out. I'm gonna have to look into that. Yeah.
- 12:40Speaker 1: Uh so you talked about the blue green light is
- 12:43Speaker 1: what they generally produce. Um, there is something called the
- 12:45Speaker 1: loose jawfish, which actually can make red light very deep
- 12:50Speaker 1: in the ocean. But that's really unusual that can make
- 12:52Speaker 1: red light, and it's um. A lot of species can't
- 12:56Speaker 1: even see the color red down there because I don't
- 12:58Speaker 1: know if they're just their brains aren't used to it
- 13:00Speaker 1: because they never see it. So the loose jaw uses
- 13:03Speaker 1: this thing um to to basically sneak up on people. Um,
- 13:09Speaker 1: it's like Jane Gum at the end of silence of
- 13:11Speaker 1: the lamb and and like the fish are like Jodie
- 13:14Speaker 1: Foster like, and Jane Gum is the loose jaw fish
- 13:19Speaker 1: coming up behind her like I can see you, you
- 13:21Speaker 1: can't see me. So, like we said earlier, we don't
- 13:25Speaker 1: know for sure why all these uh, bioluminescent forms of
- 13:30Speaker 1: life are down there doing their thing. Um. You did
- 13:34Speaker 1: mention the earthworm that has the secretion. They don't know
- 13:36Speaker 1: why they do that. The mushroom spores, they think that
- 13:41Speaker 1: maybe it's um to attract insect to spread these spores.
- 13:44Speaker 1: That's why the mushroom glows makes sense. Um Sometimes and
- 13:49Speaker 1: this one's kind of cute. Sometimes animals will light up
- 13:53Speaker 1: when something nearby them lights up, which I think might
- 13:56Speaker 1: just be a little like, hey, how you doing, I
- 13:58Speaker 1: can glow too, Well, that's how far a fliers are doing. Yeah,
- 14:01Speaker 1: they're attracting mates right with it, like a very specific
- 14:06Speaker 1: pattern right there. They used it to communicate like, hey,
- 14:10Speaker 1: you're looking pretty good. Meet you by the fence post, right, yeah, um,
- 14:14Speaker 1: let's go get some fun. So should we talk about
- 14:19Speaker 1: the dino flagellates, the dino flagellates, dino flagelates? Am I
- 14:25Speaker 1: pronouncing it wrong? No? I think that was wrong? Okay,
- 14:28Speaker 1: well yeah, So have you ever seen Apolar thirteen? Yeah?
- 14:32Speaker 1: You remember the part where um they had a problem.
- 14:35Speaker 1: Is it Tom level? Gym level? Where gym level? And
- 14:40Speaker 1: UH is hanging out with Bill Paxton and they're talking
- 14:42Speaker 1: about how they're just shooting the breeze while they're trying
- 14:46Speaker 1: to stay alive, and um he talks about how he
- 14:50Speaker 1: was flying a mission, um coming in on an aircraft carrier,
- 14:55Speaker 1: and there was a blackout and he couldn't see where
- 14:58Speaker 1: he's going, he couldn't find the aircraft carry to land.
- 15:00Speaker 1: He's running low and fuel. Then all of a sudden
- 15:02Speaker 1: he looks and he notices that there's a bunch of
- 15:05Speaker 1: um he calls it like glowing algae or whatever. But
- 15:08Speaker 1: what he's talking about where dino flagelets that were kicked
- 15:11Speaker 1: up by the wake of the aircraft carrier and he
- 15:14Speaker 1: used them as like a runway to guide them in.
- 15:17Speaker 1: I remember that part. That's a great part that whole
- 15:19Speaker 1: movie from like start to finish with. But these dino
- 15:23Speaker 1: flagelets create what's called the milky sea when you get
- 15:26Speaker 1: enough of them together, when they're disturbed physically, they start
- 15:30Speaker 1: to glow. And if you have a bunch of them,
- 15:32Speaker 1: you can see him from space. Actually in this article
- 15:34Speaker 1: there's a picture of a pretty substantial milky sea off
- 15:38Speaker 1: the coast of Africa. Pretty cool stuff. And if you
- 15:42Speaker 1: google milky Sea two you can see some like that's
- 15:45Speaker 1: cool looking. But I like the shots from like low
- 15:47Speaker 1: flying planes, helicopters and uh a little eerie. Yeah, that
- 15:53Speaker 1: may say. So. They have no idea again, why dino
- 15:56Speaker 1: flagelates would glow when they're disturbed. Obviously they're like trying
- 16:00Speaker 1: to register their complaint. They can't talk, you can't flip
- 16:04Speaker 1: anyone off, so they glow out of anger. Apparently, Um,
- 16:10Speaker 1: they they there's a theory called the burglar alarm theory.
- 16:13Speaker 1: I like this one. Or basically they think that, um,
- 16:16Speaker 1: when dino flage lets start to glow, it's because there's
- 16:20Speaker 1: little fish eating on them, right, which is disturbing. They
- 16:24Speaker 1: think that maybe they glow to basically alert larger fish
- 16:28Speaker 1: that will come eat the smaller fish so they'll stop
- 16:30Speaker 1: eating the dino flagelets. That there's little fish in the area.
- 16:34Speaker 1: Pretty awesome, Like hey, help come eat this guy because
- 16:39Speaker 1: you're bigger. Uh. Here's some other and you know, these
- 16:42Speaker 1: are the ones that are the most understood because there
- 16:45Speaker 1: is a lot of uncertainty, Like we said, like ten
- 16:47Speaker 1: times um. But here's here's some of the reasons that
- 16:51Speaker 1: they think they're doing this communication, which we've mentioned with
- 16:53Speaker 1: the firefly or the lightning bug. Uh, to locate food,
- 16:57Speaker 1: maybe to use it as an actual light to see
- 17:00Speaker 1: in the dark. Pretty cool, or a spotlight to catch prey,
- 17:04Speaker 1: oh like temporarily blind something gotcha? Or no, to like
- 17:09Speaker 1: go find it. It's very dark in here. I need
- 17:12Speaker 1: to see what fish are around to attract prey, like
- 17:15Speaker 1: the anglerfish, Like look at this bright glow, come here, chomp. Yeah.
- 17:19Speaker 1: I love that one. What was that in Finding Nemo Man?
- 17:22Speaker 1: The thing was scary. I didn't see that movie, good one, Camouflage.
- 17:27Speaker 1: I don't watch any of those anymore because Emily doesn't
- 17:29Speaker 1: like him. Oh, yes, she doesn't like Disney movies. She
- 17:32Speaker 1: doesn't like any of those Pixar movies because it's always
- 17:34Speaker 1: like some tragedy like someone dies in its heartbreak and
- 17:37Speaker 1: keep her away from toy story three. Dude, I can't
- 17:40Speaker 1: even watch that movie. I made her watch up and
- 17:42Speaker 1: she was just like a like a little blob of
- 17:44Speaker 1: play the first ten minutes or this so sad. God.
- 17:49Speaker 1: But I always explained to her, like, this is why
- 17:50Speaker 1: they make these movies, so kids can learn how to
- 17:53Speaker 1: cope with death. And then they see like it's all
- 17:54Speaker 1: happy afterwards, you know, all right, camouflage this is the
- 17:59Speaker 1: cool this one, yeah, and the it's pretty. It makes
- 18:02Speaker 1: sense too. If you're in the ocean, and if you
- 18:04Speaker 1: ever like swum down ten or fift ft and looked
- 18:07Speaker 1: up open your eyes in the ocean, I've done it. Um.
- 18:11Speaker 1: It's it's hard to see stuff below you, but it's
- 18:13Speaker 1: easy to look up because you know the sunlight's penetrating
- 18:15Speaker 1: down and see like the silhouette or in the case
- 18:18Speaker 1: of Jaws, you see like the silhouette of the lady's
- 18:20Speaker 1: legs on the raft. You know, that's good eating. Um.
- 18:24Speaker 1: If you have, like in the case of what's it
- 18:28Speaker 1: called counter elimination, you can actually produce spots on your
- 18:32Speaker 1: underside to make it more difficult for a fish beneath you,
- 18:35Speaker 1: a predator beneath you to look up and like make
- 18:38Speaker 1: out what's going on, Like, you won't have the the
- 18:41Speaker 1: the perfect little silhouette outline of a yummy fish. It'll
- 18:44Speaker 1: confuse it, basically because you're cutting down in the contrast
- 18:48Speaker 1: pretty cool, like you're creating light that blends in with
- 18:51Speaker 1: that same blue green light, and all of a sudden
- 18:54Speaker 1: you disappear well or just breaks up your shapes don't
- 18:57Speaker 1: look like you should. Um. And then there's the opposite,
- 19:01Speaker 1: the cookie cutter or cigar shark, which is the name
- 19:04Speaker 1: I think you made up, Um, that's real, which basically
- 19:08Speaker 1: has the reverse of that, where the bottom, the underside
- 19:12Speaker 1: of the cookie cutter shark glows except for this one
- 19:16Speaker 1: spot in the middle that is dark that looks like
- 19:20Speaker 1: a small fish, So of shark or some other animal
- 19:24Speaker 1: looking up, we'll be like, I'm gonna go eat that fish.
- 19:27Speaker 1: And then all of a sudden it's like, oh god,
- 19:28Speaker 1: it's a cookie cutter slash cigar shark. And then the
- 19:33Speaker 1: cookie cutter shark takes a bite out of them, round
- 19:36Speaker 1: bite and that's why they call it the cookie cutter.
- 19:38Speaker 1: It's like a little plug of flesh and if you've
- 19:41Speaker 1: ever seen google these dudes in their face, it's like
- 19:45Speaker 1: the most frightening little thing you've ever seen in your life. Yeah,
- 19:47Speaker 1: they're pretty terrifying. And you'll see pictures of like a
- 19:51Speaker 1: shark or a whale washed up on the shore with
- 19:53Speaker 1: like hundreds of these little bite plugs taken out of them. Yeah,
- 19:57Speaker 1: that's pretty awful. That's a that's a terrible way to go. Yeah,
- 20:00Speaker 1: but good for you, cigar shark, because you're small and
- 20:02Speaker 1: you're doing what you can. Tough world down there. It's
- 20:05Speaker 1: wildly you know, it's diphotic, and then self defense is
- 20:10Speaker 1: the last reason. Um And basically, like a squid may
- 20:13Speaker 1: release inc to cloud your vision, some of these things
- 20:16Speaker 1: can release a cloud of a glowing cloud two uh,
- 20:20Speaker 1: basically make you sit back and put on pink Floyd
- 20:22Speaker 1: and like chill out for a little while. Yeah, I
- 20:24Speaker 1: looked it up. There's a shrimp. There's a type of
- 20:26Speaker 1: shrimp that releases a bioluminescent cloud. And I couldn't get
- 20:31Speaker 1: the name. I saw both fire breathing and vomiting shrimp
- 20:35Speaker 1: for the common names. But yeah, it just puts it out.
- 20:39Speaker 1: That's not what I would want order on the menu,
- 20:42Speaker 1: the fried vomiting shrimp, uh, and make sure there's extra
- 20:46Speaker 1: poop in the main vain. Um. So what's going on here? How?
- 20:52Speaker 1: How is this magic happening? Well, just like we've mentioned
- 20:56Speaker 1: with a light stick, and involves two different substances mixed
- 21:00Speaker 1: together to produce this reaction. Um. And there can be
- 21:04Speaker 1: all different kinds of kinds of chemicals. But depending on
- 21:06Speaker 1: the on the fish or the being, the being, the life. Uh.
- 21:14Speaker 1: The g one is a a lucifer in and that's
- 21:18Speaker 1: the light producer, and the other is a lucif phrase
- 21:21Speaker 1: and that is the enzyme that catalyzes it. So and
- 21:25Speaker 1: those aren't specific things like you you wouldn't look at
- 21:28Speaker 1: the chemical composition of something and be like, oh, that's
- 21:30Speaker 1: lucifer in. Something can be a lucifer and it's a
- 21:34Speaker 1: generic term for something that produces light or something that
- 21:37Speaker 1: catalyzes the production of light, the lucifhrase. That is correct,
- 21:42Speaker 1: And they will mix together and a lot of times
- 21:47Speaker 1: the lucifer in is something called a photo protein and
- 21:49Speaker 1: it needs an eye on a charged ion to get
- 21:52Speaker 1: things going. That would be the lucifhrase. That's right, But
- 21:55Speaker 1: in all cases there's some sort of trigger. Could be mechanical,
- 21:58Speaker 1: could be chemical, could be neu logical startle. Yeah, it
- 22:02Speaker 1: could be something they don't understand yet, but something triggers
- 22:05Speaker 1: these two things to get together and make this reaction.
- 22:09Speaker 1: And one thing that I didn't realize was the word
- 22:12Speaker 1: Lucifer means lightbringer. Yeah, I never knew that. You mean,
- 22:17Speaker 1: I um went on a little side tear last night
- 22:20Speaker 1: trying to figure out why the devil would be named
- 22:23Speaker 1: the light Bringer? Did you find out? It's a mystery.
- 22:27Speaker 1: It's um Latin and it came years, like centuries after
- 22:32Speaker 1: UM the Old Testament was originally written, and I can't
- 22:36Speaker 1: remember what version, but it was basically like added on
- 22:38Speaker 1: by the I guess the Romans maybe added it on,
- 22:44Speaker 1: but it's because it's Latin and the original version was
- 22:47Speaker 1: not written in Latin. Lightbringer, the light Bringer, the morning Star,
- 22:52Speaker 1: that's another way to put it. They said, maybe it
- 22:55Speaker 1: had to do with Venus, because Venus is like a
- 22:59Speaker 1: false are, and so maybe Lucifer is a false angel,
- 23:05Speaker 1: is what they're saying. But makes sense because the devil
- 23:07Speaker 1: would always come in disguise. Maybe, Yeah, I think that's
- 23:10Speaker 1: weak light Bringer. That's pretty specific like what is that.
- 23:15Speaker 1: I bet there's some theologian that has the answer here.
- 23:17Speaker 1: I want to hear it. Yeah, I would hard to
- 23:19Speaker 1: find out about that one podcast at Discovery dot com
- 23:22Speaker 1: if you know that answer. So, Um, you've got lucifer in,
- 23:25Speaker 1: you've got luciphrase. Some of these chemical reactions require another substance,
- 23:30Speaker 1: and a lot of times it's oxygen, right, So luciferen
- 23:35Speaker 1: will come in in contact with an oxygen molecule and
- 23:38Speaker 1: then the luciphrase comes along, and then you've got a
- 23:42Speaker 1: bioluminescent glow, which is pretty cool. But they also think
- 23:46Speaker 1: that that's one of the reasons I should say, that's
- 23:50Speaker 1: one of the reasons why they think that bioluminescence is
- 23:54Speaker 1: an accidental byproduct of regular old evolution and that originally um,
- 24:00Speaker 1: like there's a lucifering called um ceiling terrazine. I believe
- 24:07Speaker 1: it's how you pronounce it, uh, And it's an antioxidant.
- 24:10Speaker 1: It goes around and tries to find like rogue, harmful
- 24:14Speaker 1: free radicals oxygen derivatives right and get rid of them. Uh.
- 24:22Speaker 1: And they think that this happened this was a process
- 24:27Speaker 1: that was way way older than bioluminescence, and then along
- 24:30Speaker 1: came some substance that became a lucifhrase, and then light
- 24:36Speaker 1: was created, and then it was just a byproduct like heats,
- 24:39Speaker 1: a byproduct of metabolism, right. Um. But they think also
- 24:44Speaker 1: that over time this happened in like maybe it's going
- 24:48Speaker 1: on inside of us right now and we're producing light,
- 24:51Speaker 1: but we just don't know it, or it's just so
- 24:53Speaker 1: weak that we wouldn't even possibly be able to detect it.
- 24:56Speaker 1: But this happened enough times in animals in the ocean
- 24:59Speaker 1: where suddenly ones could catch prey more easily because they
- 25:02Speaker 1: could see better than other animals that weren't bioluminescing, And
- 25:06Speaker 1: so it was selected in these skies, and now bioluminescence
- 25:10Speaker 1: is its own trait rather than a byproduct of the
- 25:14Speaker 1: antioxidant process. I bet you're right. Oh it's that's not
- 25:18Speaker 1: me man. I think you just cooked this up. I
- 25:21Speaker 1: wish that's better than why as far as research papers go, Yeah,
- 25:25Speaker 1: throw a theory out there, see if it sticks, That's
- 25:27Speaker 1: what I say. So the deal with these these animals
- 25:31Speaker 1: is they either have all this stuff like in their
- 25:33Speaker 1: body as part of them, or they have a little
- 25:37Speaker 1: relationship with a bacteria, like producing bacteria that live in
- 25:41Speaker 1: a light organ and this is pretty cool. Like some
- 25:45Speaker 1: of these animals can pull this organ back into their
- 25:47Speaker 1: body like it's always on. Sometimes they don't want to
- 25:50Speaker 1: light to be on, so they'll pull it back in
- 25:51Speaker 1: the body. Or they have a little something like a
- 25:53Speaker 1: light uh an eyelid that they can just kind of
- 25:56Speaker 1: close over the light, which is pretty amazing. Yeah, but
- 26:00Speaker 1: it's always going. Yeah. And what the other thing with
- 26:03Speaker 1: evolution is they think that because they don't see this
- 26:06Speaker 1: as often in lakes because lakes are younger, then they
- 26:09Speaker 1: think it maybe happened independently at different parts in the ocean.
- 26:13Speaker 1: So I talked to Tracy about this, and it was
- 26:15Speaker 1: a little hinky. She wrote this a long time because
- 26:17Speaker 1: she couldn't quite remember what the point was. But the
- 26:20Speaker 1: point was that they think that because the process of
- 26:24Speaker 1: antioxidation is a normal thing, um, that the the conditions
- 26:31Speaker 1: were right for bioluminescence to be selected naturally in some places,
- 26:35Speaker 1: but it wouldn't in like a lake. So the the
- 26:38Speaker 1: idea that this happened independently and spontaneously when needed through
- 26:44Speaker 1: evolution is kind of backed up by the idea that
- 26:47Speaker 1: you don't really see bioluminescence at the bottom of lakes
- 26:49Speaker 1: because you don't need it. It all makes sense when
- 26:53Speaker 1: you just peel the peel the little curtain back, don't
- 26:55Speaker 1: it when you peel the glowing skin bag? What else
- 27:00Speaker 1: you got? Anything else? You've seen glowing cats? Yeah? The
- 27:05Speaker 1: Mayo Clinic likes to put jellyfish jeans in animals. The
- 27:09Speaker 1: most the biggest one so far as a cat and
- 27:12Speaker 1: make it glow because they're checking um disease. They're using
- 27:16Speaker 1: it to mark the progression of diseases. But they made
- 27:19Speaker 1: a glowing cat. It's pretty cool, now does the I
- 27:23Speaker 1: gotta look this. It glows under a blue light, but
- 27:25Speaker 1: it glows green, and it's like the cat glows green
- 27:28Speaker 1: like it. I guess it's the hair the caratinate produces
- 27:33Speaker 1: has some sort of fluorescent property to it, but it's
- 27:36Speaker 1: it's not bioluminescent in it's fluorescent, and fluorescent is where
- 27:43Speaker 1: you take light of one color and reflected back, absorb
- 27:46Speaker 1: it and reflected back of it as a different color.
- 27:48Speaker 1: You're not actually producing light, all right. I just looked
- 27:51Speaker 1: it up. Wow, it's a glowing cat and I double
- 27:55Speaker 1: check the day, a double check the damn like, this
- 27:58Speaker 1: better not be an April Fool article. But it's not.
- 28:04Speaker 1: I want one of those this photic Yeah, okay, so
- 28:10Speaker 1: if you you're done, I'm done. Yeah. There's glowing rats too.
- 28:14Speaker 1: You know these are baby cats I think you should punch.
- 28:17Speaker 1: Are called kittens in some countries. Um, if you if
- 28:21Speaker 1: you want to learn more about bioluminescence, you should type
- 28:24Speaker 1: that in to the search bar. And you want to
- 28:26Speaker 1: type b I O l U M I N E
- 28:30Speaker 1: S C E n c E not ful in the
- 28:36Speaker 1: search bar at how stuff works dot com, and it'll
- 28:38Speaker 1: bring up this very cool article with some pretty glowing pictures. UM.
- 28:43Speaker 1: And I said, uh, search bar somewhere in there, which
- 28:46Speaker 1: means it's time for a listener mail. No it's not, Josh.
- 28:48Speaker 1: Today's part two of you want to say it? For
- 28:57Speaker 1: those of you don't know, this is a point at
- 28:59Speaker 1: the show where we um thank people for little tokens
- 29:02Speaker 1: and gifts and chatch keys and things that they have
- 29:05Speaker 1: sent us food sometimes foods, and UM, it's a good
- 29:08Speaker 1: chance to hear your name on the show as a
- 29:10Speaker 1: as a thank you, and it's a good chance for
- 29:12Speaker 1: some of you to find out where you can get
- 29:14Speaker 1: some of these things, because a lot of times they're
- 29:16Speaker 1: like really great creative, crafty things. People write books, and like,
- 29:20Speaker 1: we want to support uh crafters and writers and bakers
- 29:25Speaker 1: of cookies, and we want to support Bill Wagoner, who
- 29:29Speaker 1: sent us a bumper sticker on how to pronounce Nevada Nevada.
- 29:34Speaker 1: I'll never get used to that. It's not right. It
- 29:36Speaker 1: is right, but I tell everyone that writes in only
- 29:39Speaker 1: people from Nevada say it that way. Everyone else says
- 29:42Speaker 1: Nevada Nevada. That's Nevada, all right. Lily, her sister Toby,
- 29:48Speaker 1: and brother in law Danny start a company called Please
- 29:50Speaker 1: Be Good Humans. Yeah, I mean they've gotten uh, they
- 29:53Speaker 1: sent us some shirts. I think they sent some to
- 29:56Speaker 1: the stickers. They've got them. Know, everybody has stickers. We
- 29:59Speaker 1: passed them out. Oh well, Kristen Conger, I think that's
- 30:01Speaker 1: short too though, Oh she did. I think so. Oh
- 30:03Speaker 1: that's great. Um. And basically everything is has the p
- 30:07Speaker 1: B g H logo on it, which is like, be
- 30:12Speaker 1: good to each other, and of everything they sell goes
- 30:16Speaker 1: to the charity of your choice. So if you go there,
- 30:19Speaker 1: Please Be Good Humans. The Internet you can actually get
- 30:23Speaker 1: some of the stuff and choose your own charity that
- 30:27Speaker 1: will go to. Very nice message, Very nice. Um, how
- 30:29Speaker 1: about some Randy Carbonny action. Yeah, he send us his
- 30:34Speaker 1: Pirate Gag booklet, which is a tailor made for Pirate Day.
- 30:39Speaker 1: Talk about too Pirate Day. If you want to learn
- 30:42Speaker 1: more about that, you could go to Pirate Day p
- 30:46Speaker 1: I R A T E A d A y dot
- 30:50Speaker 1: blog spot dot com and hook up with Randy carbon Action.
- 30:56Speaker 1: Christopher M. A Roth with an E at the end
- 30:59Speaker 1: sent us a kN version of his book Dirk Danger
- 31:02Speaker 1: Loves Life. I don't have a kindle yet, and I'm
- 31:04Speaker 1: dying to read this thing, just sitting there. Um. Susannah
- 31:10Speaker 1: from Archie the Archie Comics. Um, she sent us a
- 31:14Speaker 1: bunch of stuff. She she she sends us stuff in
- 31:17Speaker 1: like waves. I guess you could put it. But most recently, um,
- 31:20Speaker 1: she sent us a Archie meets Kiss hardcover book of
- 31:24Speaker 1: Kevin Keller book. Um, that's the first gay character. That's right,
- 31:29Speaker 1: first gay comic book character. This whole green lantern hubbub.
- 31:33Speaker 1: I haven't heard that. Oh yeah, there's apparently two green lanterns,
- 31:36Speaker 1: and one of them came out as gay and it's
- 31:38Speaker 1: just a man in the comic that he came out.
- 31:41Speaker 1: And yeah, but Archie's gotta beat it's right because of
- 31:46Speaker 1: Kevin Keller is the first gay character UH in the
- 31:49Speaker 1: Jinx comics that Susannah is she draw right produced those
- 31:52Speaker 1: which yeah, I mean that's her baby, So UM support
- 31:55Speaker 1: the Jinx comics and Archie's a whole. She sent his
- 31:58Speaker 1: shirts and what we're supposed to meet at UH Comic Con,
- 32:01Speaker 1: but she said they were slammed in the booth and
- 32:03Speaker 1: she was unable to get away. Oh I met Uncle
- 32:06Speaker 1: John's Reader people. From reader People, they gave us shirts
- 32:09Speaker 1: and hats, very nice, so thank you for that as well.
- 32:13Speaker 1: We're from Mad Magazine too. Just like floored me. Yeah,
- 32:18Speaker 1: did you write that guy back? I totally did you. Yeah,
- 32:20Speaker 1: I finally did. Um. Daniel Mackenzie from Oakland, California Sennison
- 32:25Speaker 1: LP from his band shut I Unison, awesome music, indie rock,
- 32:31Speaker 1: little noisy, little melodic, right up my alley, shut Out Unison.
- 32:36Speaker 1: I didn't see that one. It's good stuff. Um. Andy
- 32:39Speaker 1: Parr Sentison edition of Games Magazine's World of Puzzles. Is
- 32:44Speaker 1: that the one that had us as a clue. I believe.
- 32:47Speaker 1: So yeah, stuff you should know was a clue in
- 32:50Speaker 1: a word search. I believe nobody got it. I don't
- 32:54Speaker 1: get this one. That's cool, but it was very nice
- 32:56Speaker 1: that he uh he did. He went to that in trouble.
- 32:59Speaker 1: Uh Suki s u k I Design Laboratory, senter some
- 33:02Speaker 1: hankies and this was the lady who designed the baby
- 33:08Speaker 1: head T shirt with the fly. Yeah, our favorite T
- 33:10Speaker 1: shirt of the submissions, the most disturbing one. It was
- 33:14Speaker 1: one of my five favorites. It was my favorite inning. Yeah.
- 33:17Speaker 1: But um, she designed that, and she sent us some
- 33:20Speaker 1: hankies with like these hankies have like sleeping sickness and
- 33:24Speaker 1: hepatitis and like the chemical combinations of these on the hanky.
- 33:29Speaker 1: Yeah that's what's contained within. Yeah, that's pretty awesome. Um yeah,
- 33:34Speaker 1: thank you for those. Duff Man sent it's the Springfield
- 33:37Speaker 1: Isotopes couzy. Yeah, from deaf Man himself. Yeah, uh, we
- 33:42Speaker 1: appreciate that, sir. Uh. Silver Fox broad Band sent his
- 33:46Speaker 1: Silver Fox T shirts and at first I was all, well,
- 33:49Speaker 1: is this broadband company sending his shirts? Then I looked
- 33:51Speaker 1: up they supply internet for senior homes, So I was
- 33:56Speaker 1: all of a sudden work with pride. Everyone at my
- 33:59Speaker 1: gym thinks that I'm a silver Fox. Comfortable. Let's see
- 34:06Speaker 1: the guys from rock tail Ours send us a T
- 34:08Speaker 1: shirt the podcast about rock music. Um, that's rock and
- 34:13Speaker 1: then tail t a l e our check them out.
- 34:16Speaker 1: Bike rappers dot com uh with w R A p
- 34:20Speaker 1: B are not rapping like music. They sent us some
- 34:23Speaker 1: reflective bike rappers and dog collars. Basically just these little
- 34:27Speaker 1: bell grow things. Such an easy invention but but necessary
- 34:31Speaker 1: and you wrap them on the frame of your bike
- 34:34Speaker 1: to make your bike more reflective. And they have a
- 34:36Speaker 1: little reflective dog collars too. It's pretty cool. Um, we've
- 34:40Speaker 1: got Christmas cards from a bunch of people. Thank you
- 34:43Speaker 1: very much. From this is how far behind we are.
- 34:45Speaker 1: It's Christmas in July, everybody, Nick and Lindsay Devon, b
- 34:49Speaker 1: Becca Evans, Andrew and Janelle Thomas. So thank you very much.
- 34:53Speaker 1: Merry Christmas all your people, and happy Halloween. M oh
- 34:58Speaker 1: and I've got one more and send us a Halloween car.
- 35:00Speaker 1: Oh thanks, Happy Halloween, am. And then again from Nick
- 35:03Speaker 1: and Lindsay. They sent us Valentine State cards. Yeah, they're
- 35:06Speaker 1: they're pretty sweet. They send us stuff are you done,
- 35:08Speaker 1: because I got two more in this one. Let's go
- 35:10Speaker 1: for it, dude. David Beaver's family has been making a
- 35:14Speaker 1: magnetic calendar for fifty years, and not just one. They've
- 35:17Speaker 1: been making the magnetic calendars for fifty years. Uh. The
- 35:22Speaker 1: Magnetic Calendar dot com owned operated, made and sourced in
- 35:26Speaker 1: the Midwest. It's a selling point family business. They've been
- 35:30Speaker 1: doing this for how long fifty years? Fifty years? Uh?
- 35:33Speaker 1: And then Jill Swing sent us a Twinkie the kid
- 35:35Speaker 1: t shirts, So thank you very much. Yeah, I believe
- 35:37Speaker 1: it was how many design to write? I don't know,
- 35:40Speaker 1: I think it is, was it? Yeah? Well, thank you everybody.
- 35:42Speaker 1: That was very kind of you. Yeah. We have one
- 35:44Speaker 1: more installment and they'll here soon, and then I have
- 35:48Speaker 1: to do it because these are all the ones that
- 35:49Speaker 1: Chuck compiled. I think it's most of them that you
- 35:51Speaker 1: have a lot. I've got a decent amount. All right. Well,
- 35:55Speaker 1: then they'll be apart four, okay, and then we'll start
- 35:57Speaker 1: all over all right, all right? If you want to
- 36:00Speaker 1: send us something, even something is innocuous, is just a hello.
