The bullhead triplefin (Trianectes bucephalus) is a fish of the family Tripterygiidae and only member of the genus Trianectes
Its length is up to about 7 cm. [2]
This nocturnal species is infrequently observed, during the day it often shelters beneath small rocks. [3]
The bullhead triplefin is found in the eastern Indian Ocean around southern Australia, from Western Australia to Victoria and Tasmania at depths down to 5 m. The animal inhabits intertidal areas. [2]

The largemouth triplefin, Ucla xenogrammus, is a fish of the family Tripterygiidae and only member of the genus Ucla, found in the Pacific Ocean from Viet Nam, the Philippines, Palau and the Caroline Islands to Papua New Guinea, Australia, and the Solomon Islands, Fiji, Tonga, east to American Samoa and Rapa Iti, at depths of between 2 and 41 metres. Its length is up to about 47 millimetres (1.9 in). The generic name was coined by ichthyologist Richard Heinrich Rosenblatt in his unpublished dissertation of 1959 from the University of California Los Angeles and it is the initials of that institution, it was formally applied by Holleman in 1993.
Apopterygion alta, known commonly as the tasselled triplefin, is a species of triplefin blenny. It is endemic to the waters off south-eastern Australia from northern Tasmania to Port Phillip in Victoria. It is normally observed on yellow sponges.

The northern yellow-black triplefin, also known as the northern Australian yellow-black triplefin, is a species of triplefin blenny in the genus Enneapterygius. 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). Male northern yellow-black triplefins can reach a maximum length of 2.8 centimetres.
The halfblack triplefin, also known as the half-black triplefin, blackbelly triplefin, or the green-tail threefin, is a species of triplefin blenny in the genus Enneapterygius. It was originally described by R. Kner and F. Steindachner in 1867. It is a non-migratory tropical blenny known from coral reefs in the western Pacific Ocean, and has been described from the Ryukyu Islands to eastern Australia. It has been recorded swimming at a depth range of 0–30 metres.
Enneapterygius larsonae, known commonly as the Western Australian black-head triplefin, is a species of triplefin blenny in the genus Enneapterygius. It was described by the German ichthyologist Ronald Fricke in 1994. The specific name honours Helen K. Larson, the Curator of Fishes at the Museum and Art Gallery of the Northern Territory in Darwin, Australia, who collected the type.
Enneapterygius philippinus, the minute triplefin, is a species of triplefin blenny in the genus Enneapterygius. It was described by Wilhelm Peters in 1868. This species occurs in the Indo-Pacific from Christmas Island to Samoa, and from the Ryukyu Islands in the north south to Australia.
Enneapterygius similis, known commonly as the black and red triplefin, blacktail triplefin or masked threefin, is a species of triplefin blenny in the genus Enneapterygius. It was described by Ronald Fricke in 1997. This species occurs in the western central Pacific Ocean, from the Ryukyu Islands south through the Philippines, in Sabah, central Indonesia, Shepard Island, New Caledonia and eastern Australia.
Enneapterygius triserialis, the white-spotted triplefin, is a species of triplefin blenny in the genus Enneapterygius. It was described by Ronald Fricke in 1994.

Lepidoblennius haplodactylus, known commonly as the eastern jumping blenny, is a species of triplefin blenny in the genus Lepidoblennius. It was described by Franz Steindachner in 1867 and is the type species of the genus Lepidoblennius.
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 leeuwin, known commonly as the Leeuwin triplefin, is a species of triplefin blenny in the genus Norfolkia. It was described by Ronald Fricke in 1994. This species is found in the southern part of the coast of Western Australia from the Houtmon's Abrolhos Islands to the Recherche Archipelago. It is found in rocky reefs. Its specific name references the Leeuwin Current which influences the coastal areas in which this fish occurs.
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.
Springerichthys kulbickii, known commonly as the Kulbicki's triplefin, is a species of triplefin blenny in the genus Springerichthys. It was described by Ronald Fricke and John E. Randall in 1994, honouring the fish ecologist reef-fish ecologist Michel L. Kulbicki of L'Office de la Recherche Scientifique et Technique d’Outre-Mer in Nouméa, who collected type in New Caledonia, in its specific name. Kulbicki's triplefin is found in the southwestern Pacific Ocean from Queensland, Australia across the central Pacific to the Samoa, where it is found on rocky and coral reefs down to 15 metres (49 ft) in depth.
Trinorfolkia clarkei, known commonly as the Clarke's triplefin or Clarke's threefin, is a species of triplefin blenny in the genus Trinorfolkia. It was described by Alexander Morton in 1888 from specimens collected from Clarke Island in the Bass Strait. This species occurs I southern and western Australia from Camden Haven in New South Wales to Rottnest Island in Western Australia and around Tasmania. It occurs on coastal reefs and in estuaries frequently being observed around the pylons supporting structures such as jetties.
Trinorfolkia cristata, known commonly as the crested triplefin or crested threefin, is a species of triplefin blenny in the genus Trinorfolkia. It was described by Rudie Kuiter in 1986. This species is endemic to the coasts of South Australia from Sceale Bay to Victor Harbor, including Kangaroo Island. It is found in rocky reefs from the intertidal zone to a depth of 15 metres (49 ft), among boulders, on vertical rock walls and on man-made structures such as piers and jetties.
Trinorfolkia incisa, known commonly as the notched triplefin or notched threefin, is a species of triplefin blenny in the genus Trinorfolkia. It was described by Rudie Kuiter in 1986. This species is found at depths of between 10 and 30 metres on the roofs of caves. This species occurs along the southern coast of Australia from the south western coast of Western Australia to Victoria and around Tasmania.
