These giants feed on similar to baleen whales, filtering thousands of cubic meters of water through a “net launcher”. which has become Horny Gill stamens of these sharks. Remaining in the oral cavity Maso and Munro – plankton (except for especially large objects) and serves as food sharks planktophagous. Just today there are three such shark: giant whale, which the inhabitants of epipelagial, and largemouth tending to mesopelagial, for depths greater than 150 m.

These sharks differ from individuals of other species by a number of morphological features associated with the specifics of the production of food. First of all here should stay on the morphology of the Gill apparatus sharks planktophagous, Except a kind of Gill rakers, they have a very large mouth, largemouth and whale sharks is almost final. Epipelagic sharks-planktology filter huge amounts of water and thus receive the necessary amount of food in places of mass accumulations of planktonic organisms,so the whale and especially of basking sharks clearly feed migration.

largemouth gulability shark living at great depths, where plankton concentration is more sparse, much harder. This forced her to go on an intensive way of feeding.
