The black-throated triplefin is a species of triplefin blenny in the genus Helcogramma. It was described by Allan Riverstone McCulloch and Edgar Ravenswood Waite in 1918. This species occurs along the western and southern coasts of Australia where it is found down to depths of 13 metres (43 ft) in both the intertidal and subtidal zones where it hides among algae growing on rocky substrates.
The triangle triplefin is a species of triplefin blenny in the genus Helcogramma. It was described by Henry Weed Fowler in 1946. This species occurs in the western Pacific Ocean in the Ryukyu Islands, Taiwan and islands in Batangas province in the Philippines.
The helmet triplefin is a species of triplefin blenny in the genus Helcogramma. It was described by Fricke in 1997. This species is endemic to the islands of Komodo, Lombok, Nusa Tenggara Barat and Timor in Indonesia.
Helcogramma springeri, known commonly as the Springer's triplefin, is a species of triplefin blenny in the genus Helcogramma. It was described by P.E. Hadley Hansen in 1986. The specific name honours the ichthyologist Victor G. Springer of the National Museum of Natural History. This species is found in the western Pacific Ocean from Indonesia and the Philippines to northern Australia, including the Great Barrier Reef.
The twinspot triplefin is a species of triplefin blenny in the genus Lepidonectes. It was described by Gerald R. Allen and David Ross Robertson in 1992. This species is found in the eastern Pacific Ocean where it has been recorded only in the vicinity of Malpelo Island in Colombia. The twinspot triplefin acts as a cleaner fish, its only client species being the grouper Epinephelus labriformis.
The signal triplefin is a species of triplefin blenny in the genus Lepidonectes. It was described by William Albert Bussing in 1991 and he gave it a specific name which honours the American ichthyologist Clark Hubbs (1921–2008). This species occurs in the eastern Pacific Ocean where it is found off Costa Rica and Panama. The signal triplefin is found on rocky shores where it feeds on very small invertebrates and algae.
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.
