The Caribbean
sharpnose shark has a slender fusiform body and long
snout. The long labial furrows are present around the
corners of the mouth. The first dorsal fin is typically
over or just behind the free tips of the pectoral fins;
the origin of the second dorsal fin is either just over
the anal fin midbase to over the rear quarter of its
base. The anterior margin of the pectoral fins is usually
a bit longer than the first dorsal length from origin
to free rear tip. The origin of the anal fin is anterior
to the second dorsal fin origin. The margin of the anal
fin is either straight or slightly concave.
