The Centrophoridae are a family of squaliform sharks. The family contains just two genera and about 15 species. They are sometimes called gulper sharks, but this is also the name of a specific species in the family, Centrophorus granulosus. These are generally deepwater fish. While some, such as the gulper shark C. granulosus, are found worldwide and fished commercially, others are uncommon and little-known. Their usual prey is other fish; some are known to feed on squid, octopus, and shrimp. Some species live on the bottom (benthic), while others are pelagic. They are ovoviviparous, with the female retaining the egg-cases in her body until they hatch.
Astroscopus guttatus is a fish that can reach lengths of 22 inches (56 cm) and is found on the Atlantic shores between the states of North Carolina and New York in the United States. The northern stargazer can be found up to depths of 120 feet (37 m). Stargazers have a flat forehead with a lot of body mass up front near the mouth.
The stargazers are a family, Uranoscopidae, of perciform fish that have eyes on top of their heads. The family includes about 51 species in eight genera, all marine and found worldwide in shallow and deep saltwaters.
The convict cichlid is a fish species from the family Cichlidae, native to Central America, also known as the zebra cichlid. Convict cichlids are popular aquarium fish and have also been the subject of numerous studies on fish behaviour.
Deania is a genus of long-snouted, deepwater dogfish sharks in the family Centrophoridae.
In biology, the electric organ is an organ that an electric fish uses to create an electric field. Electric organs are derived from modified muscle or in some cases nerve tissue, and have evolved at least six times among the elasmobranchs and teleosts. These fish use their electric discharges for navigation, communication, mating, defence, and in strongly electric fish also for the incapacitation of prey.
Epigonus telescopus, the black cardinal fish, is a species of deepwater cardinalfish found in most temperate oceans worldwide, at depths of between 75 and 1,200 metres though mostly between 300 and 800 metres. It can reach a length of 75 centimetres (30 in) TL though most specimens do not exceed 55 centimetres (22 in) TL. It has been reported that this species can reach an age of 104 years.
The white-bodied catshark is a catshark of the family Scyliorhinidae.
The broadmouth catshark is a rare catshark of the family Scyliorhinidae, the holotype and only specimen of which was taken from off Zhujiang in the South China Sea, at a depth of 913 m. Its length is around 38 cm. The broadmouth catshark's reproduction is oviparous. Considering the species is not well known, the threats are not known either but may be deepwater fisheries.
Callionymus is a genus of dragonets found mostly in the Indian and Pacific oceans with a few species occurring in the Atlantic Ocean.
The Lake Victoria deepwater catfish is a species of catfish of the family Clariidae. It is monotypic within the genus Xenoclarias. This species is endemic to Lake Victoria, and is found in deeper areas of the lake, from 12 to 20 metres (39–66 ft). This species is threatened with extinction or may already be extinct due to predation by the introduced Nile perch as well as other recent ecological changes. This species grows to about 20 cm (7.9 in) SL.
Dactyloscopus is a genus of sand stargazers native to the coasts of the Americas.
Coastal fish, also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf. Since the continental shelf is usually less than 200 metres (660 ft) deep, it follows that pelagic coastal fish are generally epipelagic fish, inhabiting the sunlit epipelagic zone. Coastal fish can be contrasted with oceanic fish or offshore fish, which inhabit the deep seas beyond the continental shelves.
Uranoscopus is a genus of stargazer fish from the family Uranoscopidae. The name Uranoscopus is from the Greek, ouranos, "sky" and skopein, "to watch".
Astroscopus, the electric stargazers, is a genus of stargazers, a type of percomorph fish from the family Uranoscopidae, part of the order Trachiniformes. The species in this genus are anatomically distinct Uranoscopids, being characterized by internal nares and being the only group of marine bony fish having organs which produce electricity which are derived from the extraocular muscles. They are found on the Atlantic and Pacific coasts of the Americas.
Kathetostoma is a genus of bony fish from the family Uranoscopidae, the stargazers. They are demersal predators which are found in the western Atlantic, Pacific and Indian Oceans, with most species around Australia and New Zealand.
The black-barred wrasse is a species of ray-finned fish, a wrasse from the family Labridae which is native to the southwestern Pacific Ocean.
Kathetostoma canaster, also known as the speckled stargazer, is a fish species described in 1987. It is native to the Eastern Indian Ocean.
