The Blue Shark

The Blue Shark is one of the most beautiful of all sharks. Unfortunately, it’s also one of the most over fished sharks in the world. Also known as the Prionace Glauca, they are easy to identify because of their special slim, torpedo shaped figures. Their swimming is very elegant and they are known to be exquisite swimmers. They reach up to 4 meters in length (13 feet) and weight up to 205 kilograms (450 pounds).

Sensory System

Like all other shark species, they have a special sense of feeling with and organ called theampullae of Lorenzini. They are able to track their prey through electro magnetic pulse that all living creatures emit. They can even sense your heart beating from several miles away!

Hunting Behavior

The species prefers to eat squid. But they will consume much more than that, including bony fish, smaller sharks, sea birds, shrimp, and lobster.

Offspring

This is a Viviparous shark, which means the pup shark develops in the uterus. Females give live births to 20 to 100 pups at once.

The courtship between males and females is quite violent. Male sharks often bite females so female skin is 3 times as thick as a males skin.

Relationship with Humans

This is the most fished shark of all shark species. They are used for their fins, shark skin, tails, and flesh. Sometimes their teeth and jaws are taken for commercial uses as well. There has been much concern recently about over fishing from both commercial fisheries as well as game fisheries. Approximately 10 to 20 million of these sharks are killed due to human capture every year. This species has no other natural enemies besides Humans.

This species is non aggressive towards humans. The only known attacks are the result of the shark feeling threatened or biting after a human capture of the shark.
