Hoplostethus fedorovi is a small deep-sea fish species belonging to the slimehead family (Trachichthyidae).
It is found in the Western Central Pacific (a holotype from the Marcus-Necker ridge). [2] [3]
Hoplostethus fedorovi is recorded to be found within a marine environment within a bathypelagic or benthopelagic depth range. [4] [5] This species is occupied in the depth range of about 500 – 520 meters. They are commonly known to be a deep water species. [3] [6] [7]
Hoplostethus fedorovi was can reach the maximum recorded length of about 15.9 centimeters or about 6.25 inches as an unsexed male. [3]
Hoplostethus fedorovi serves as no threat to humans. They are recorded to be a harmless species. [8]
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 ± 25 metres at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. If Mount Everest were placed into the trench at this point, its peak would still be underwater by more than 2 kilometres (1.2 mi).
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 snailfishes or sea snails are a family of marine ray-finned fishes. These fishes make up the Liparidae, which is classified within the order Scorpaeniformes.
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 orange roughy, also known as the red roughy, slimehead and deep sea perch, is a relatively large deep-sea fish belonging to the slimehead family (Trachichthyidae). The UK Marine Conservation Society has categorized orange roughy as "vulnerable to exploitation". It is found in 3 to 9 °C, deep waters of the Western Pacific Ocean, eastern Atlantic Ocean, Indo-Pacific, and in the eastern Pacific off Chile. The orange roughy is notable for its extraordinary lifespan, attaining over 200 years. It is important to commercial deep-trawl fisheries. The fish is a bright, brick-red color, fading to a yellowish-orange after death.
Fangtooths are beryciform fish of the family Anoplogastridae that live in the deep sea. The name is from the Greek anoplo, meaning "unarmed", and γαστήρ, meaning "stomach". With a circumglobal distribution in tropical and cold-temperate waters, the family contains only two very similar species in one genus, with no known close relatives.
Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that do live on or near the bottom, and reef fish that are associated with coral reefs.
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches. The hadal zone ranges from around 6 to 11 km below sea level, and exists in long, narrow, topographic V-shaped depressions.
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes. They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word demersal comes from the Latin demergere, which means to sink.
The shorthorn fangtooth is a species of fangtooth found in the tropical waters of the Atlantic and Pacific Oceans at depths down to 1,500 metres (4,900 ft).
The mandarin dogfish is a dogfish, a member of the family Squalidae in the order Squaliformes. It is found at depths of 140–650 metres (460–2,130 ft) off southern Japan, Taiwan, and Indonesia. Populations off Australia and New Zealand were formerly included in this species, but in 2007 these were assigned to a new species, the southern mandarin dogfish. It is not clear which of these species is involved in other populations from the tropical West Pacific.
The white-spotted Izak or African spotted catshark is a catshark of the family Scyliorhinidae. It is found in the western Indian Ocean off the coasts of Natal, South Africa, southern Mozambique, Madagascar, Kenya, and Tanzania between latitudes 4° S and 37° S, at depths of between 220 and 440 m. It can grow up to 35 cm in length.
Myripristis vittata is a soldierfish from the Indo-Pacific.
Saurida umeyoshii is a species of lizardfish that lives in the Pacific Ocean.
The diamond lizardfish(Synodus synodus) is a species of lizardfish that lives in tropical and subtropical waters of the Atlantic Ocean.
Bathyprion danae, the fangtooth smooth-head, is a species of slickhead found in deep waters of the Atlantic and Pacific Oceans. It is in the monotypic genus Bathyprion.
Hoplostethus is a genus of fish in the slimehead family.
Hoplostethus vniro is a small deep-sea fish species belonging to the slimehead family (Trachichthyidae). It is found in the eastern Central Atlantic in marine environment within a bathydemersal depth range, which is a deep-water habitat. This species reaches the average length of about 19.6 centimetres (7.7 in).
Hoplostethus tenebricus is a small deep-sea fish species belonging to the slimehead family (Trachichthyidae).
Hoplostethus rubellopterus, is a small deep-sea fish species belonging to the slimehead family (Trachichthyidae).
