The megamouth shark has luminous organs called photophores around its mouth. As opposed to predators who seek out specialized food items, filter feeding is simply opening up your mouth and taking in whatever happens to be there, while filtering out the undesirable parts. Water is expelled through a single osculum at a velocity of about 8.5cm/second: a jet force capable of carrying waste products some distance away from the sponge. Baleen whales feed either by skimming the water and trapping prey on the fringe-like hairs of their baleen or gulping in large quantities of water and prey and then forcing the water out, leaving prey trapped inside. Whale Sharks, Basking Sharks, and Megamouth Sharks all grow to massive lengths, they all eat by filtering out plankton from the sea water.
