Summary: Blue sharks are epipelagic, oceanic, and found in warm seas worldwide. They sometimes occur near the coast where the shelf narrows or is cut by submarine canyons close to shore. This is probably the most wide-ranging of all sharks, being found throughout tropical and temperate seas from 60N to 50S latitude.

The maximum reported size for blue sharks is about 13 feet, but blue sharks taken off the U.S. West Coast average much smaller and are seldom over 8 ft. Maximum age is estimated to be at least 20 years.

These images of blue shark, Prionace glauca, were taken off the coast of southern California near the Channel Islands.
