Sharks, rays, and skates have no lungs; lungs had not developed in animals until later. “Skates and rays primarily feed in or on the ocean floor by biting off pieces of sessile invertebrates or excavating buried prey, although they will also feed in the water column.” Rays and skates dig out their buried prey by flapping their pectoral fins to stir up the dirt on the ocean floor.

It has a mouth full of small, sharp, almost scale-like teeth. We're too slow, too encumbered with gear, and often too stupid to be much more than prey. These eating machines should also be left to the professional sport fisherman. Some people are scared of sharks and although we hear about shark attacks on humans, they are actually rare. This shark can also maintain a body temperature warmer than the water surrounding it, a trait it shares with its relatives: makos and great whites. Color is light brown above, shading to white on underside.

One Australian box jellyfish can have dozens of tentacles, each up to 15 feet long, with enough toxin to kill 60 people. Unlike many mammals, the shark’s nostrils are used purely for smell as opposed to breathing, and are located on the underside of their snout.

Fish market surveys of the kind that resulted in the rediscovery of the smoothtooth blacktip are an increasingly common research tool that offers many advantages over traditional scientific field sampling.
