Blue Shark




Prionace glauca


The blue shark is one of the most abundant and far-ranging of all sharks and is a prolific breeder. Females sometimes litter as many as 70 pups. This is a slimly built fish with a 2 m specimen weighing only about 32 kg. Regarded by anglers as a sport fish, the current world angling record is 3.5 m and 186 kg. Sometimes known as the blue whaler because of its frequent presence at the scene of a whale kill, the blue shark is not reputed to be particularly dangerous to humans.
