Shark meat is a seafood consisting of the flesh of sharks. Several sharks are fished for human consumption, such as porbeagles, shortfin mako shark, requiem shark, and thresher shark, among others. [1] Shark meat is popular in Asia, where it is often consumed dried, smoked, or salted. [2]
Smaller sharks eat proportionately more cephalopods and crustaceans, switching to fish as they grow older. [ 10 ] [ 16 ] Many predators feed on the milk shark, including larger sharks such as the blacktip shark ( Carcharhinus limbatus ) and Australian blacktip shark ( Carcharhinus tilstoni ), and possibly also marine mammals .

However sharks lack swim bladders, and maintain their buoyancy instead with large livers that are full of oil. [10] This stored oil may also function as a nutrient when food is scarce. [11] Deep sea sharks are usually targeted for their oil, because the livers of these species can account for up to 5–10% of their total weight. [1]
Thresher sharks are solitary creatures that keep to themselves. It is known that thresher populations of the Indian Ocean are separated by depth and space according to sex. Some species however do occasionally hunt in a group of two or three contrary to their solitary nature. All species are noted for their highly migratory or oceanodromous habits.
The Port Jackson shark is a nocturnal species which peaks in activity during the late evening hours before midnight and decreases in activity before sunrise. [2] A study showed that captive and wild individuals displayed similar movement patterns and the sharks' movements were affected by time of day, sex, and sex-specific migrational behaviour.

These sharks eat mostly teleost fishes (particularly myctophids), cephalopods and crustaceans. [6] Females produce a maximum of one to two pups every one to two years. Newborn pups range in size from 35 cm to 40 cm. Evidence suggests that the left-side uterus is less functional than the right-side. [7] They can live up to 46 years on average.
Ever since the movie "Jaws" popularized great white sharks as predatory man-killers, people have had misconceptions about these animals. That is why researchers have been doing everything they can ...
