Although the Silky shark is mainly found in the pelagic zone, the Silky shark is not just found in the open ocean, but has also been recorded from depths as shallow as 18 meters (56 ft). It is an active, swift shark that prefers warmer waters (about 23°C). It is commonly found near the edges of continental shelves and over deep water reefs where there is a large amount of food source. It mainly ranges from the surface down to at least 500 meters (1,550 ft) but has been caught over water as deep as 4000 meters (12,400 ft). Studies show that groups of Silky sharks contain Silky sharks of different genders, but of the same size. Young Silky sharks can be found in coastal nurseries and adults are found further offshore, over deeper waters.
