Deep Sea 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
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.
