Description

The Oblique-swimming triplefin is a triplefin (Tripterygiidae) from coastal waters around New Zealand. The species grows to about 6 cm and has an elongate body with three separate dorsal fins. Unlike most triplefins it hovers obliquely in open water above the reef. As a bottom-dweller it perches on rocks, weed and sand of shallow coastal water and picks small invertebrates. The fish is harmless to humans.
