The blue shark is a pelagic (living in the open ocean) fish that is found worldwide. It is one of the fastest fish in the sea, with a sleek, tapered body that is made for agile, graceful swimming. The tail fin moves from side to side, which also enables the blue shark to swim powerfully. It will pursue its prey for long distances, and can even leap out of the water.

The blue shark has pointy, serrated teeth so that it can successfully catch even slippery fish. Its favorite prey is squid, but if these are not readily available, the blue shark feeds on any other prey it finds.

Blue sharks are viviparous, meaning they give birth to live young. Their average litter size is twenty-five to fifty pups at a time, but has been seen to reach up to one hundred and thirty-four!

The blue shark’s natural predators include California sea lions, shortfin makos, white sharks and sometimes killer whales. Humans also hunt blue sharks, for sport fishing or for practical uses — the skin for leather, the liver for oil and the fins for shark-fin soup. Their flesh is also edible, but it is not in much demand.
