 A small shark typically measuring long, the blacknose has a typical streamlined "requiem shark" shape with a long, rounded snout, large eyes, and a small first dorsal fin.Its common name comes from a characteristic black blotch on the tip of its snout, though this may be indistinct in older individuals.Blacknose sharks feed primarily on small bony fishes and cephalopods, and in turn fall prey to larger sharks.
