Generally, carnivores such as sharks have shorter intestines compared to herbivores. Instead, sharks have spiral valves, which increase the surface area of the intestine. Mouth-Since sharks swallow food as a whole or as large pieces, very little physical digestion happens in the mouth. Therefore, there is no report on secretion of digestive juices in the mouth. Esophagus-Connects the oral cavity and pharynx with the stomach online. Although its mouth is huge, its gullet is small and limits the size of prey that it can swallow. The whale shark is a filter feeder and its modified gill rakers can remove food particles from sea water down to 1 mm (0.039 in) in diameter, but most of its food comes in larger dimensions. Along with the small forms of phytoplankton and zooplankton that are caught in its filtering system it will also eat sea jellies, small crustaceans, squid, and small fishes such as anchovies, sardines, mackerel, and similar species Participatory analysis, monitoring and evaluation for fishing communities: A manual (FAO Fisheries Technical Papers) balancestudios.net.

The rise in demand for shark products increases pressure on fisheries.

[108] A study by the International Union for Conservation of Nature suggests that one quarter of all known species of sharks and rays are threatened by extinction and 25 species were classified as critically endangered. [109] [110] Other threats include habitat alteration, damage and loss from coastal development, pollution and the impact of fisheries on the seabed and prey species. [111] The 2007 documentary, Sharkwater exposed how sharks are being hunted to extinction. [112] In 1991, South Africa was the first country in the world to declare Great White sharks a legally protected species. [113] Intending to ban the practice of shark finning while at sea, the United States Congress passed the Shark Finning Prohibition Act in 2000.
