Blue Shark

World Record ~ 528 Lbs Caught at Montauk Point, NY on Aug. 9, 2001 by angler Joe Seidel

Scientific name ~ Prionace Glauca

Other names ~ Blue Shark, Blue Dog , Blue Whaler

Identification ~ The blue shark's name comes from its distinct dark blue dorsal surface and bright blue sides. Its ventral surface is a well-defined, crisp white color. The blue shark has a slender, sleek-looking body with a large eye and a long conical snout that is longer than the width of its mouth. It has extremely long, pointed pectoral fins, which generally are as long as the distance from its snout to posterior gill slit. The dorsal fin is moderate in size and set back

Size ~  The Blue Shark can reach 13 feet in length. Males are believed to be mature at four to five years of age and at lengths between 6 feet  and 8 feet. Females mature at slightly older ages ranging from five to six years and longer lengths from 7-10 feet. They are believed to live for more than 20 years.

Habitat ~ Being a pelagic species the blue shark's habitat consists of open ocean areas from the surface to 1,148 ft in depth. They prefer cooler water ranging from 44 F to 60 F but are known to have tolerances for water 69 F or greater. When in the tropics the blue shark tends to seek deeper waters with cooler temperatures. Blue sharks are found world wide in temperate and tropical waters. They are a pelagic species that rarely comes near shore but have been known to frequent inshore areas around oceanic islands and locations where the continental shelf is narrow. In the Atlantic they can be found from New Foundland, Canada to Argentina and from Norway to South Africa, including the Mediterranean. They range from South Africa to Indonesia and from Japan to New Zealand in the Indian and western Pacific Oceans. In the eastern Pacific, blue sharks range from the Gulf of Alaska to Chile.

Feeding Habits ~ The Blue Shark feeds on small bony fishes, such as herring and sardines, and invertebrates, such as squid, cuttlefish and pelagic octopi, make up a majority of the blue shark's diet. They easily feed on certain species of squid that form large breeding aggregations, which allows the blue shark to leisurely collect its unsuspecting prey. Besides actively hunting for food, blue sharks are opportunistic feeders and have been known to feed from gill nets and scavenge dead marine mammals.
