These Animals Are Breaking the Species Barrier
It's a wild world out there, and animals are constantly surprising us by breaking the species barrier. Take the "iguana mermaids," for example—marine iguanas native to the Galápagos Islands that have evolved to swim underwater, resembling miniature aquatic dragons. Then there's the fascinating case of ligers and tigons, hybrids of lions and tigers, blending the characteristics of both majestic big cats. Don't forget about narlugas, the rare hybrid offspring of narwhals and beluga whales, sporting the narwhal's iconic tusk and the beluga's rounded head.
