Mako sharks have flexible denticles that move to lower the resistance of water in places that will offer the most resistance (the gills) where flow separation exists. Flow separation is where water passes over a structure quickly and then slow down to form tiny eddies. The flexibility in the denticles offers less resistance and takes away the flow separation allowing the shark to…
