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.

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.

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.
