The Black-tailed triplefin (Tripterygion melanurum) is a saltwater fish of the family Tripterygiidae that grows up to 5 cm.
Description
The black-tailed triplefin is a very small, blenny-like rock fish of the family Tripterygiidae reaching at most about 5 cm. It is characterised by the three separate dorsal fins that give the group its name. The brownish body shows dark cross-bars and, in breeding males, a dark head and tail. Unlike most triplefins this species favours shaded places: it lives on dark rock faces, under overhangs and in caves of the Mediterranean and the adjacent eastern Atlantic. It hunts small crustaceans and invertebrates. The male defends a territory and guards the eggs laid on the rock. Because of its small size it has no fishery importance.
