The megamouth shark (Megachasma pelagios) was unknown to science until 1976. It is an extremely rare species of deepwater shark, and the smallest of the three planktivorous sharks, besides the whale shark and basking shark. Since its discovery, few megamouths have been seen, with 60 specimens known to have been caught or sighted. Like the other two filter-feeders, it swims with its enormous mouth wide open, filtering plankton and jellyfish from the water column.
