Blue Shark

Blue sharks (Prionace glauca) are a species of requiem shark, in the family Carcharhinidae. They inhabit deep waters in the world’s temperate and tropical oceans. They prefer cool waters and migrate long distances, such as from New England to South America. The species is listed as Near Threatened by the IUCN. They can move quickly and feed primarily on small fish and squid, although they can take larger prey.

Blue sharks have long pectoral fins and are countershaded: the top of the body is deep blue, lighter on the sides, and the underside is white. The male blue shark commonly grows to 1.82 to 2.82 m (6.0 to 9.3 ft) at maturity, whereas the larger females commonly grow to 2.2 to 3.3 m (7.2 to 10.8 ft) at maturity. The blue shark is fairly elongated and slender in build and typically weighs from 60-121lbs (27-55kg) in males and from 205-401lbs (93-182 kg) in large females.
