Identification of the Blue Shark:
The blue shark is a long, lean shark that can grow as long as 3.8 meters. The body of the blue shark has a white underbelly, lighter sides, and a deep, almost iridescent blue colour on the back. The pectoral fins, which are exceptionally long and slender, have a trailing edge that is much behind the dorsal fin, which is situated rather low. Blue sharks have huge eyes with a distinct white ring around the edge and a long, cone-shaped snout.
Biology:
The birth rate of blue sharks is viviparous, with each litter containing anywhere from 4 to 135 young. Females reach sexual maturity at a size of 7 to 11 feet, while for males it is achieved at lengths of 6 to 9 feet, about 6 years old.
Behaviour:
A pelagic species that can be found in all of the world’s oceans, these sharks prefer the more temperate temperatures between 12 and 21 °C.
Scuba Diving:
Offshore, practically everywhere in South Africa is home to these sharks. Pelagic shark species can be found in the Cape Town area throughout the summer months for divers who are ready for an offshore experience.
Blue and mako sharks may be found some 10-20Nm off Cape Point in the months from October to May.
