The Spinner Shark (Carcharhinus brevipinna Müller & Henle, 1839) is a species of the family Carcharhinidae. They are found in tropical and warm temperate waters around the globe, except for the eastern part of the Pacific Ocean. Both inhabit the waters off the coast that, up to depths of 100 meters, although they prefer shallow waters. It looks like, though as the larger version, the shark edged or blacktip shark (Carcharhinus limbatus). The average length is 2 meters, the body mass of 56 kg. The record for the species belongs to a specimen of about 3 meters and 90 kg.

It is quick and gregarious predators that feed on a variety of bony fishes and cephalopods. When feeding in a group, they pass quickly through the bed by rotating around its own axis and out partially from the water. At this habit you have the English name spinner shark. Prey when they are alone are captured and swallowed whole, because the dentition of the species to be cut is rather lacking. The shape of the teeth and staining of specimens vary significantly with age and geographic region, giving rise to confusion in the classification.
Like other Carcharhinidae the species is viviparous, adult females have a single functional ovary, but two wombs, which give birth to 3 to 20 sharks each year. The newborns are raised in areas specially selected by the species near the coast and grow in a rather fast. In principle, these sharks are not dangerous to humans. They themselves do not perceive the great mammals as prey because their fine teeth are better suited to grasp that to cut. They may, however, enter into a state of excitement in the presence of food, therefore it is always recommended caution while spearfishing. Until 2008, the International Shark Attack File has taken note of 16 unprovoked attacks and one caused attributable to the species in question. None of the attacks was fatal.
Their value for commercial fishing is rather high, both for meat and for the liver oil and the skin.
Other synonimus are: Aprionodon caparti, Carcharhinus johnsoni, Carcharias brevipinna, Isogomphodon maculipinnis, Longmania calamaria, Uranga nasuta.
