With prey often scarce in its oceanic environment, the silky shark is a swift, inquisitive, and persistent hunter.
It feeds mainly on bony fishes and cephalopods, and has been known to drive them into compacted schools before launching open-mouthed, slashing attacks.
Silky sharks are highly mobile and migratory, though the details of their movements are little-known.A scientific description of the silky shark was first published by the German biologists Johannes Müller and Jakob Henle under the name Carcharias (Prionodon) falciformis, in their 1839 Systematische Beschreibung der Plagiostomen. The silky shark has a cosmopolitan distribution in marine waters warmer than 23 °C (73 °F). It occurs throughout the Indian Ocean, as far south as Mozambique in the west and Western Australia in the east, including the Red Sea and the Persian Gulf.Subsequent authors have assigned this species to the genus Carcharhinus. In the Pacific Ocean, the northern extent of its range runs from southern China and Japan to southern Baja California and the Gulf of California, while the southern extent runs from Sydney, Australia, to northern New Zealand to northern Chile.It can be distinguished from other large requiem sharks by its relatively small first dorsal fin with a curving rear margin, its tiny second dorsal fin with a long free rear tip, and its long, sickle-shaped pectoral fins.It is a deep, metallic bronze-gray above and white below.
