[11] [13] Sharks are also killed for their flesh in Europe and elsewhere. [14] The 2007 film Sharkwater documents ways in which sharks are being hunted to extinction. [15] In 2009, the IUCN Shark Specialist Group reported on the conservation status of pelagic (open water) sharks and rays. They found that over half the pelagic sharks targeted by ...
The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
Whale sharks inhabit waters of roughly 1,000 meters depth regularly, which suggests it could be a regular form of food fall in areas where it is abundant. [30] Many eelpouts (Zoarcidae) were found surrounding the whale shark with some evidence of direct feeding as boreholes were observed on the carcass.
While sharks sit near the top of the food chain in the ocean, their extinction would still have an effect on our life. Without sharks, the ecosystem would be thrown off, triggering changes to the ...
[62] [63] Levels of pollutants in toothed-whale products are significantly higher than those of baleen whales, [64] reflecting the fact that toothed whales feed at a higher trophic level than baleen whales in the food chain (other high-up animals such as sharks, swordfish and large tuna show similarly high levels of mercury contamination).

Orcas in the Gulf of California appear to have gained special skills to hunt and kill the world’s largest fish, according to a new study.. Whale sharks, which grow up to 18m long, are known to ...
A giant shark that was known as a megalodon use to terrorize the underwater world. Although the enormous sharks didn't make the evolutionary cut, researchers believe they still had a big impact on ...
The majority of shark nets used are gillnets, which is a wall of netting that hangs in the water and captures the targeted sharks by entanglement. [6] The nets may be as much as 186 metres (610 ft) long, set at a depth of 6 metres (20 ft), have a mesh size of 500 millimetres (20 in) and are designed to catch sharks longer than 2 metres (6.6 ft) in length.
