The great blacktip shark , also known as spinner shark or long-nosed shark ( Carcharhinus brevipinna ), belongs to the family of requiem sharks (Charcharhinidae).
The great blacktip shark is a 1.9 to 2.7 meter tall, slender shark with a pointed snout and a relatively small first dorsal fin. The color is gray-bronze on the back and whitish on the belly. A whitish band runs across the flanks and the dorsal , pectoral and anal fins , as well as the lower part of the caudal fin, have striking black tips.
The second name spinner shark comes from the fact that it is a fast- swimming species that often jumps out of the water when hunting for schools of fish. In addition to schooling fish such as sardines , herrings and tuna , its food spectrum also includes molluscs , as well as smaller sharks and rays .
Widespread, almost worldwide on the continental shelf.

Southern Mediterranean off the coast of North Africa, Capverdean Islands, Sierra Leone down to Angola. Indian Ocean : Southeast Africa, Madagascar , Seychelles . Red Sea , Gulf of Aden. Western Central Pacific and also Australia . Missing in the island regions of the Pacific .
The great blacktip shark is viviparous with three to 15 offspring per litter.
