Apopterygion is a genus of triplefins in the family Tripterygiidae. It has two described species.
Threefin or triplefin blennies are blenniiforms, small percomorph marine fish of the family Tripterygiidae. Found in tropical and temperate waters of the Atlantic, Pacific and Indian Oceans, the family contains about 150 species in 30 genera. The family name derives from the Greek tripteros meaning "with three wings".
The yellow-and-black triplefin, Forsterygion flavonigrum, a triplefin of the genus Forsterygion, is found around the north of the North Island of New Zealand at depths of between 15 and 30 m, in reef areas of broken rock. Its length is between 4 and 7 cm.
The oblique-swimming triplefin, Forsterygion maryannae, is a triplefin, found along the north east coast of the North Island of New Zealand from depths of about 5 m to 50 m. They are the only triplefins not to spend most of their time resting on the bottom, instead swimming in loose schools of up to hundreds of individuals above rocky reefs. When swimming their head is higher than the tail, giving rise to their common name.
Helcogramma is a genus in the triplefin family Tripterygiidae. The blennies in the genus Helcogramma are found throughout the Indo-Pacific and in the South Atlantic Ocean off the islands of St Helena and Ascension.
Helcogramma striatum, commonly called the tropical striped triplefin, the striped threefin or the neon triplefin, is a triplefin blenny of the genus Helcogramma, native from the central Indo-Pacific.
Enneapterygius is a genus of fish in the family Tripterygiidae found in the Indian and Pacific Ocean.
Ceratobregma is a genus of triplefins in the family Tripterygiidae.
Enneanectes is a genus of triplefin fish in the family Tripterygiidae.
Helcogrammoides is a genus of triplefins in the family Tripterygiidae. The species in this genus are found in South America and the Antarctic Peninsula.
The southern barred triplefin, Brachynectes fasciatus, is a triplefin of the family Tripterygiidae and only member of the genus Brachynectes, found around Australia's south coast including Tasmania at depths down to 13 m. Its length is only up to about 41 mm.
The lizard triplefin, Crocodilichthys gracilis, is a fish of the family Tripterygiidae and only member of the genus Crocodilichthys, found in the Gulf of California in the eastern Central Pacific at depths down to 38 m. Its length is only up to about 64 mm.
The giant triplefin, Blennodon dorsale, is a triplefin of the family Tripterygiidae, the only member of the genus Blennodon, found around the coast of New Zealand. It length is up to 15 cm, and it is the largest known triplefin species.
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.
Axoclinus cocoensis, known commonly as the Cocos triplefin, is a species of triplefin blenny. It is found only on shallow reefs around Cocos Island in the eastern Pacific Ocean, part of Costa Rica.
Enneapterygius clarkae, the barred triplefin, is a species of threefin blenny in the genus Enneapterygius. It was described by Wouter Holleman in 1982, and was given its species epithet in honour of American ichthyologist Eugenie Clark (1922-2015) It is a tropical blenny known from the Indian Ocean, and has been described from the Red Sea to Natal, South Africa. Male barred triplefins can reach a maximum length of 2.5 centimetres.
Enneapterygius clea, or Clea's triplefin, is a species of threefin blenny in the genus Enneapterygius, described by German ichthyologist Ronald Fricke in 1997. It is endemic to Queensland, Australia.
Enneapterygius flavoccipitis, the yellownape triplefin or northern bicoloured triplefin, in Australia, is a species of threefin blenny in the genus Enneapterygius.
Enneapterygius rufopileus, the blackcheek threefin, Lord Howe black-head triplefin or redcap triplefin, is a species of triplefin blenny in the genus Enneapterygius. It was described by Edgar Ravenswood Waite in 1904. It occurs in the western Pacific Ocean off Lord Howe Island, Norfolk Island, New Caledonia, Fiji and Tonga.
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.
