The Tetraodontiformes are an order of highly derived ray-finned fish, also called the Plectognathi. Sometimes these are classified as a suborder of the order Perciformes. The Tetraodontiformes are represented by 10 extant families and at least 349 species overall; most are marine and dwell in and around tropical coral reefs, but a few species are found in freshwater streams and estuaries. They have no close relatives, and descend from a line of coral-dwelling species that emerged around 80 million years ago.
In most biological nomenclature, a scale is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopteran species, scales are plates on the surface of the insect wing, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function.
The Liparidae, commonly known as snailfish or sea snails, are a family of marine scorpaeniform fishes.
The reef triggerfish, also known as the rectangular triggerfish, wedgetail triggerfish, or by its Hawaiian name humuhumunukunukuāpuaʻa, also spelled humuhumunukunukuapua'a or just humuhumu for short, is one of several species of triggerfish. It is found at reefs in the Indo-Pacific and is the state fish of Hawaii.
is an extinct genus of shark-like holocephalian which lived from the Late Devonian to Late Carboniferous epoch, dying out around 298.9 million years ago. Fossils have been found in Asia, Europe and North America.

Psarolepis is a genus of extinct lobe-finned fish which lived around 397 to 418 million years ago. Fossils of Psarolepis have been found mainly in South China and described by paleontologist Xiaobo Yu in 1998. It is not known certainly in which group Psarolepis belongs, but paleontologists agree that it probably is a basal genus and seems to be close to the common ancestor of lobe-finned and ray-finned fishes. In 2001, paleontologist John A. Long compared Psarolepis with Onychodontiform fishes and refer to their relationships.
Liparis, commonly known as widelip orchids, sphinx orchids or 羊耳蒜属 is a cosmopolitan genus of more than 350 species of orchids in the family Orchidaceae. Plants in this genus are terrestrial, lithophytic or epiphytic herbs with a wide range of forms. The flowers are usually resupinate and small to medium sized, yellow, yellow-green or purplish with spreading sepals and petals. The labellum is usually larger than the sepals and petals and is lobed, sometimes with a toothed or wavy margin and one or two calli at its base.
Campbellodus decipiens is an extinct ptyctodontid placoderm fish that lived around 380 million years ago. Its fossil remains have been found preserved in perfect three-dimensional form from the Gogo Formation of Western Australia. Originally it was described from large tooth plates and isolated skull roof bones by Miles & Young (1977). Long (1995) restored the complete fish based on new material found at Gogo in the mid 1980s, and described by Long (1997).
Abyssobrotula galatheae, is a species of cusk eel in the family Ophidiidae. It is the deepest-living fish known; one specimen, trawled from a depth of 8,370 m (27,460 ft) in the Puerto Rico Trench in 1970, holds the record for the deepest fish ever captured. Although generally recognized, some have suggested that the record-breaking individual might have been caught with a non-closing net and therefore perhaps caught shallower.
Pachycostasaurus is an extinct Pliosauroid from the Oxford Clay formation of Peterborough, England.
Liparis fabricii, commonly known as the gelatinous seasnail or gelatinous snailfish, is a benthopelagic species of snailfish from the Arctic Ocean. It has a tadpole-like body with a maximum length of about 20 cm (7.9 in). It is brown to black in coloration with a distinctive dark peritoneum. It preys on small crustaceans and marine worms. It is not commercially important, though it is a valuable food source for predatory fish and seabirds in the Arctic region.
Liparis is a large genus of snailfish from the northern hemisphere. They are very common in temperate and cold waters. Chernova (2008) has proposed that the genus should be subdivided into five subgenera: Liparis, Neoliparis, Lycocara, Careliparis, and Lyoliparis.
The Atlantic seasnail or Atlantic snailfish is a fish belonging to the genus Liparis. It is a small tadpole-like fish with a soft, scaleless body and complex ventral sucker. The ventral fins have been re purposed to be a sucker. They have a single dorsal fin with about six spines differentiated from the soft rays by a slight notch. This species reaches a maximum length of about 5 inches. It ranges from Newfoundland to New Jersey. The Atlantic seasnail lives in the immediately subtidal region to depths of 183 m In northern parts of its range, it is found on the shore line. It breeds in mid-winter, the eggs being laid amongst hydroid growths on the sea bed, and on stony ground. Its food is mainly small crustaceans, particularly shrimps, but occasionally small fishes are eaten.
Liparis antarcticus is a fish from the genus Liparis. It is a marine fish that lives in the demersal zone. Liparis antarcticus can be found in the Southeast Pacific Ocean by Chile, and it is the only known species from its genus to live in the Southern Hemisphere.
Liparis brashnikovi is a fish from the genus Liparis. The fish grows to a maximum of 15 cm. It is a marine fish that lives in the demersal zone. Distribution includes the Sea of Japan in the Northwest Pacific Ocean.
Liparis bristolensis is a marine fish from the genus Liparis. It lives in the demersal zone at a depth between thirty-one to seventy-seven meters. The species may be found in the Northwest Pacific Ocean, specifically in the South Bering Sea and the western Gulf of Alaska.
Liparis burkei is a fish from the genus Liparis. It lives in shallow waters in marine environments in the demersal zone. Liparis burkei grows to a maximum length of 8.3 cm and is found in the Northwestern Pacific Ocean by Japan.
Antarctilamna is an extinct genus of Devonian shark originally exemplified by Antarctilamna prisca from South Eastern Australia and Antarctica. The latest occurring described species is Antarctilamna ultima from the Waterloo Farm lagerstätte in South Africa. Antarctilamna has robust ctenacanthid-like spines which lack a deep insertion area, and are borne in front of the first dorsal fin; in addition to distinctive diplodont teeth with small intermediate cusps. Antarctilamna-like spines, known from the Bunga Beds locality in Australia have been ascribed to A. Prisca.
