What sharks eat?
Among the modern sharks should first be noted epipelagic planktophagous of being the largest members of the superorder, class, and all living groups participatng animals. 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. Mouth largemouth sharks revealed very wide, and the mouth lined with silver foil furnace, which, apparently, glows in the dark. As many interzonals fish and invertebrates (the main prey sharks) are characterized by positive phototropism, they focus in front of the mouth of the predator, which only from time to time to close your mouth and swallow prey.
Sharks of the open ocean are active predators, among them widespread mass species: blue, long-armed, Fox shark, porbeagle, two species of sharks-the Mako and the great white shark; meet here, especially over banks and the seamounts, and some grey sharks. The species are predators in the traditional ichthyologists sense of the word, i.e. a basis of their diet consists of various species of cartilaginous and bony fish and some other sea animals.
