Cetichthys is a genus of flabby whalefishes, [1] which was first described in 1989 by John R. Paxton. [2]
There are currently two recognized species in this genus: [1]
Anomalopidae are a family of fish distinguished by bioluminescent organs located underneath their eyes, for which they are named. These light organs contain luminous bacteria and can be "shut off" by the fish using either a dark lid or by being drawn into a pouch. They are used to communicate, attract prey, and evade predators.
The Beryciformes are a poorly-understood order of carnivorous ray-finned fishes consisting of 7 families, 30 genera, and 161 species. They feed on small fish and invertebrates. Beyond this, little is known about the biology of most member species because of their nocturnal habits and deepwater habitats. All beryciform species are marine and most live in tropical to temperate, deepwater environments. Most live on the continental shelf and continental slope, with some species being found as deep as 2,000 m (6,600 ft). Some species move closer to the surface at night, while others live entirely in shallow water and are nocturnal, hiding in rock crevices and caves during the day. Several species are mesopelagic and bathypelagic. Beryciformes' bodies are deep and mildly compressed, typically with large eyes that help them see in darker waters. Colors range from red to yellow and brown to black, and sizes range from 8–61 cm (3.1–24.0 in). Member genera include the alfonsinos, squirrelfishes, flashlight fishes, fangtooth fishes, spinyfins, pineconefishes, redfishes, roughies, and slimeheads. A number of member species are caught commercially, including the alfonsino, the splendid alfonsino, and the orange roughy, the latter being much more economically important. Some species have bioluminescent bacteria contained in pockets of skin or in light organs near the eyes, including the anomalopids and monocentrids.
The beardfishes consist of a single extant genus, Polymixia, of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. They are classified in their own order Polymixiiformes. But as Nelson says, "few groups have been shifted back and forth as frequently as this one, and they were recently added to Paracanthoptergii". For instance, they have previously been classified as belonging to the Beryciformes. They are of little economic importance.
The Cetomimiformes or whalefishes are an order of small, deep-sea ray-finned fish. Some authorities include the whalefishes as part of the order Stephanoberyciformes, within the superfamily Cetomimoidea. Their sister order, the Beryciformes, includes the flashlight fish and squirrelfish.
Cetomimidae is a family of small, deep-sea cetomimiform fish. They are among the most deep-living fish known, with some species recorded at depths in excess of 3,500 m (11,500 ft). Females are known as flabby whalefishes, Males are known as bignose fishes, while juveniles are known as tapetails and were formerly thought to be in a separate family, dubbed Mirapinnidae. Adults exhibit extreme sexual dimorphism, and the adult males were once thought to be exemplars of still another family, Megalomycteridae.
The Stephanoberyciformes are an order of marine ray-finned fishes, consisting of about 68 species, the majority (61) of which belong to the ridgehead family (Melamphaidae). The Stephanoberyciformes are mostly uncommon deep-sea species with little, if any, importance to commercial fishery. They share many morphological similarities with the Beryciformes, their sister order.
Ophichthidae is a family of fish in the order Anguilliformes, commonly known as the snake eels. The term "Ophichthidae" comes from Greek ophis ("serpent") and ichthys ("fish"). Snake eels are also burrowing eels. They are named for their physical appearance, as they have long, cylindrical, snake-like bodies. This family is found worldwide in tropical to warm temperate waters. They inhabit a wide range of habitats, from coastal shallows and even rivers, to depths below 800 m (2,600 ft). Most species are bottom dwellers, hiding in mud or sand to capture their prey of crustaceans and small fish, but some are pelagic.
The velvet whalefish is a deep-sea whalefish, the sole known member of its family Barbourisiidae. It is found throughout the tropical and temperate parts of the world's oceans, mainly in the Pacific near Japan and New Zealand, at depths of 300–2,000 m. This species seems very closely related to some flabby whalefish and it was initially believed to belong to that family by some. They have been found from 65°N–40°S in the Atlantic, 50°N–50°S in the Pacific, and 5–20°S in the Indian Ocean.
Dascyllus is a genus of fish in the family Pomacentridae. They are usually commensals with corals.
The redmouth whalefishes are two species of deep-sea whalefishes in the genus Rondeletia, the only genus in the family Rondeletiidae. They are apparently close to the velvet whalefish, and apparently also to the gibberfishes (Gibberichthyidae). The latter and the Rondeletiidae are the only known living fishes which have the mysterious Tominaga's organ.
Gyrinomimus is a genus of flabby whalefishes.
Champion's tree mouse is a species of rodent in the family Muridae. It is found only in Papua New Guinea.
The Guadalcanal rat is a species of rodent in the family Muridae. It was found only in the Solomon Islands. Since this species was collected between 1886 and 1888 it has not been seen again. It is possibly extinct.
Carnarvonchochlea exigua, more commonly known as Jardinella exigua is a small freshwater snail residing in North East Queensland, near Carnarvon Gorge. Carnarvoncochlea refers to the location of origin, whilst exigua derives from the latin word "exigus" meaning "small".
Batocara is a genus of phacopid trilobites in the family Encrinuridae. The type species, B. bowningi, was described originally as Encrinurus bowningi by Foerste in 1888. In 1980, D.L. Strusz erected Batocara for 'Encrinurus' bowningi. Batocara also contains the species B. borenorense and B. fritillum.
Danacetichthys galathenus is a species of flabby whalefish found in the ocean depths at around 1,330 metres (4,360 ft). This species grows to a length of 5.4 centimetres (2.1 in) SL.
Parataeniophorus is a genus of flabby whalefishes that was formerly included in the no longer recognized tapetail family Mirapinnidae.
Rhamphocetichthys savagei, Savage's bird-snouted whalefish, is a species of flabby whalefish found at depths of around 2,100 metres (6,900 ft). It is the only known member of its genus.
Punia is a genus of cicadas in the family Cicadidae endemic to Australia. Members of the genus are called grass pygmies. There are currently five described species in Punia. They are found in Western Australia, the Northern Territory and Queensland. The genus was considered to be a monotypic genus only containing P. minima until the 2020 description of four congeners.
Cetichthys indagator is a species of flabby whalefish in the family Cetomimidae and was first described in 1959 by Robert Rees Harry-Rofen asCetomimus indagator In 1989, it was transferred to the genus, Cetichthys by John R. Paxton.
