The megamouth shark (Megachasma pelagios) is one of the most mysterious and least understood of all the sharks. It was first recorded in 1976 and is so different from other shark lineages that it has been placed in its own family: Megachasmidae. Megamouth sharks can reach over 5 metres in length; the head is large with a short snout and, as the name would suggest, an extremely large mouth. The mouth contains over 50 rows of very small, hooked teeth.
Megamouth Shark - This shark is an extremely rare and unusual species of deep water shark. Discovered in 1976, only a few have ever been seen, with 39 specimens known to have been caught or sighted as of 2007 and three recordings on film. Like the basking shark and whale shark, it is a filter feeder, and swims with its enormous mouth wide open, filtering water for plankton and jellyfish.
The Monster of the Sea Asain Sheepshead Wrasse Underwater photographer Ikuo Nakamura has been photographing the seas around Japan for over 40 years. One of his life's goals has been to capture on camera one particular giant fish -- the Asian sheepshead wrasse. This over one meter in length fish with large protrusions commands the sea with its imposing dignity.
