A large, slender shark with a moderately long, flattened, rounded snout and large eyes. Silky Sharks are grey to bluish-grey above, white below, and have a low second dorsal fin with a very long rear tip. This is the only species in the genus Carcharhinus with an interdorsal ridge in which the dorsal fin originates behind the free rear tips of the pectoral fin.

These aggressive, fast-moving sharks are considered dangerous to humans.
