Blacknose
sharks are a relatively small species of shark. The
color on their back and sides ranges from gray to gray-green
to brown, and because of this coloration blacknose sharks
are often confused with lemon sharks. There is a distinctive
dark spot on the tip of the snout, though it tends to
fade with age. The second dorsal fin and tail fin have
dark tips.
They have the elongate, sleek bodies common of the requiem
family of sharks. Both the first dorsal fin and the
pectoral fins are small, and the upper lobe of the tail
fin is longer than the lower lobe. The snout is long
and the gill slits are short.
