When swimming their head is higher than the tail, giving rise to their common name.

It was described by German Ichthyologist Ronald Fricke in 1994. It is a tropical blenny, endemic to northern Australia, in the western Pacific and southeastern Indian Oceans. It is a non-migratory species which dwells in shallow tidal pools on coralline rock and in seagrass, and has been recorded swimming at a depth range of 0–15 m (0–50 ft).

Forsterygion capito, known commonly as the spotted robust triplefin, is a species of triplefin blenny in the genus Forsterygion. It was described by Jenyns in 1842. This species is endemic to New Zealand where it occurs around the North and South Islands, Stewart Island, Auckland Islands, Snares Islands, Antipodes Islands and Chatham Islands. The adults occur along sheltered coastal reefs and in harbours and bays with substrates consisting of rock and shell. They range in depth from intertidal pools to 12 metres (39 ft), or more. They prey on small benthic animals which are swallowed whole.
