Slender requiem shark, with a pointed (or narrowly rounded) and noticeably stiff snout (hence its name!). Eyes relatively large (about 1.8 to 2.5% of total body length). First dorsal fin is small and falcate with a very long rear tip. Origin over or slightly anterior to the free rear tips of the pectoral fins. Second dorsal fin low (about 1.2 to 2% of total length) with a long rear tip, too. Origin well behind the origin of anal fin. Pectoral fins are small and falcate, with narrowly rounded or pointed tips. No interdorsal ridge present.

 Coloration

Grey to grey-brown upper body, white belly. No conspicuous fin markings, second dorsal fin"s anterior margin and both margins of the upper caudal fin sometimes have dark edges. Posterior margins of some fins, in particular the pectoral and lower caudal fin often have pale edges.
