Spinner shark - Carcharhinus brevipinna
[ video ]
A remarkable hunting technique of this active, fast-swimming shark gives it its common name: it will speed upward through a school of fish with its mouth open while spinning on its axis, emerging completely from the water.Although the maximum known size is known to be 10 feet, the average adult attains a length of just over 6 feet. Found in subtropical and warm temperate waters around the world except the eastern Pacific, the spinner shark forms schools, and the northwest Atlantic population migrates inshore during the summer months to feed and reproduce. Because of confusion with the blacktip shark, there is some uncertainty in the distribution data for this species. Throughout its range, particularly in the southeastern United States, the spinner shark is considered Near Threatened by the IUCN due to its popularity among recreational and commercial fisheries; it is prized for its fins, liver oil, flesh, and skin.
