Description

The megamouth shark is a very rare, large deep-sea shark (Megachasmidae) that occurs widely in tropical and temperate oceans but is rarely seen. The species grows to about 5.5 metres and has a sluggish, dark-grey body with an enormous, broad mouth and soft, rubbery lips. Like only two other sharks it is a filter feeder: it swims through the water column with its mouth open and strains small crustaceans and jellyfish. It migrates daily between deep and shallower water. The fish is harmless to humans.
