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]
Octopuses are the predominant food source of the whiskery shark. The whiskery shark is an active and highly specialized predator , feeding almost exclusively on octopuses . [ 9 ] Other cephalopods , bony fishes , small rock lobsters , spoon worms , and seagrass have also been found amongst its stomach contents.
Sharks' fins are sold dried, cooked, wet, and frozen. Ready-to-eat shark fin soup is also readily available in Asian markets. [9] Dried fins come in cooked and skinned (shredded) and raw and unskinned (whole), the latter requiring more preparation. [10] Both need to be softened before they can be used to prepare soup.
Unlike most sharks and other vertebrates, which have hard tissues like spines that form growth rings (much like the rings inside a tree trunk), Greenland sharks lack these structures, making age ...
Greenland sharks have also been found with remains of moose, polar bear, horse, and reindeer (in one case an entire reindeer body) in their stomachs. [12] [25] [21] The Greenland shark is known to be a scavenger and is attracted by the smell of rotting meat in the water. The sharks have frequently been observed gathering around fishing boats. [12]
“There were no sharks — ever — in the arena,” says Bartsch. “It would've been very hard to transport sharks for one thing, given that they'd have to be transported in water vessels.”
