Deep Sea Sharks
Sharks are a valuable part of marine ecosystems. Most sharks are vulnerable to overfishing because they are long-lived, take many years to mature, and only have a few young at a time. Recovery from overfishing can take years or decades for many shark species.
About 350 species of sharks occur worldwide.
Sharks are primarily oceanic and are widespread
in tropical to temperate zones. Sharks vary
greatly in size. The largest species, also the largest of
all fishes, is the plankton eating giant the Whale
Shark (Rhincodon typus). The largest measured specimen
was 12.65 m long and weighed 21.5 tonnes, but the Whale Shark
probably attains 18 metres. Some of the deepwater shark species
attain only about 25cm.
