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

The variable triplefin or striped triplefin, Forsterygion varium, is a triplefin native to New Zealand, but also introduced to Tasmania, Australia, most likely in shipments of oysters. It is found in rock pools and depths down to 30 metres, in reef areas of broken rock with kelp.
The mottled triplefin, Forsterygion malcolmi, is a triplefin of the genus Forsterygion, found around New Zealand at depths down to 30 m, in reef areas of broken rock. Its specific name honours Malcolm Francis of the Fisheries Research Centre in Wellington, New Zealand, who joined Hardy on his trips to collect specimens.

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.
Forsterygion gymnotum, known commonly as the Tasmanian robust triplefin, is a species of triplefin blenny in the genus Forsterygion. It is native to coastal New Zealand, but has also been Introduced to Tasmania, Australia. It was described by Eric Oswald Scott in 1977 from Tasmania. It is thought to have reached Tasmania from New Zealand through shipments of osyters.
Helcogramma chica, known commonly as the little hooded triplefin, is a species of triplefin blenny in the genus Helcogramma. It was described by Richard Rosenblatt in 1960. This species is found in the Indo-Pacific from the Cocos (Keeling) Islands to the Society Islands in French Polynesia.
Helcogramma vulcana, the volcano triplefin, is a species of triplefin blenny in the genus Helcogramma. It was described by John E. Randall and Eugenie Clark in 1993. This species is found in the western Pacific Ocean where it has been recorded from Bali to Gunung Api and Manuk in the Banda Sea.
Matanui bathytaton, known commonly as the Chatham deep-water triplefin, is a species of triplefin blenny in the genus Matanui. It was described by Graham S. Hardy in 1989. This species occurs at depths between 12 and 550 metres on waters off New Zealand including the Chatham Rise, southeast South Island, Auckland Islands, Antipodes Islands and Stewart Island.
Norfolkia brachylepis, known commonly as the tropical scaly-headed triplefin, is a species of triplefin blenny in the genus Norfolkia. It was described by Leonard Schultz in 1960. This is an Indo-Pacific species which is distributed from the Red Sea to Fiji, north to the Izu Islands and south to Australia.
Norfolkia squamiceps, known commonly as the Scalyhead triplefin, is a species of triplefin blenny in the genus Norfolkia. It was described by Allan Riverstone McCulloch and Edgar Ravenswood Waite in 1916. Under the synonym Norfolkia lairdi it was the type species of Fowler's new genus. This species has been recorded from off Queensland, Norfolk Island, Lord Howe Island, New Caledonia and the Loyalty Islands. The adults occur in tidal pools among areas of coral reef.
Norfolkia thomasi, known commonly as the Thomas' triplefin, is a species of triplefin blenny in the genus Norfolkia. It was described by Gilbert Percy Whitley in 1964, naming it in honour of Leonard Rees Thomas who organised the Australian Museum's 1962 Swain Reefs Expedition. The hemispherical eggs of the Thomas' triplefin are covered in sticky threads that help anchor them in the algae on their nesting sites. This adaption helps insure the safety of the eggs. One the eggs hatch the larvae that emerge are planktonic and they stick to shallow waters near the shore. The matured Thomas' triplefin then ventures out into the coral reef and intertidal pools. This species is found in the western Pacific Ocean from the Ryukyu Islands to the Tuamoto Archipelago, in Australia it is distributed from the northern Great Barrier Reef south to Byron Bay, New South Wales.
