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.
The Dalatiidae are the family of kitefin sharks of the order Squaliformes. Members of this family are small, under 2 m (6.6 ft) long, and are found worldwide. They have cigar-shaped bodies with narrow heads and rounded snouts. Several species have specialized bioluminescent organs. Though eight genera are in this family, four of them are monotypic.
Cardinalfishes are a family, Apogonidae, of ray-finned fishes found in the Atlantic, Indian, and Pacific Oceans; they are chiefly marine, but some species are found in brackish water and a few are found in fresh water. A handful of species are kept in the aquarium and are popular as small, peaceful, and colourful fish. The family includes about 370 species.
Clarias is a genus of catfishes of the family Clariidae, the airbreathing catfishes. The name is derived from the Greek chlaros, which means lively, in reference to the ability of the fish to live for a long time out of water.
The Pacific Dover sole, also called the slime sole or slippery sole, is a Pacific flatfish of the flounder family which ranges from Baja California to the Bering Sea. It takes its name from a resemblance to the common sole of Europe, which is often called Dover sole.
Deania is a genus of long-snouted, deepwater dogfish sharks in the family Centrophoridae.
The lemon sole is a flatfish of the family Pleuronectidae. It is native to shallow seas around Northern Europe, where it lives on stony bottoms down to depths of about 1,400 metres (4,600 ft). It grows up to 65 centimetres (26 in) in length and reaches about 19 kilograms (42 lb) in weight.
The spined pygmy shark is a species of squaliform shark in the family Dalatiidae found widely in all oceans. Growing no larger than roughly 28 cm (11 in), it is one of the smallest sharks alive, with this record beaten by the dwarf lanternshark. This shark has a slender, cigar-shaped body with a sizable conical snout, a long but low second dorsal fin, and an almost symmetrical caudal fin. Its sister species S. aliae and it are the only sharks with a spine on the first dorsal fin and not the second. Spined pygmy sharks are dark brown to black, with numerous bioluminescent organs called photophores on their ventral surface. The shark is believed to use these photophores to match ambient light conditions, which break up its silhouette and help the shark to avoid being seen by predators below.
Coryphaenoides is a genus of rattails which is found in all oceans of the world. They are found in deep waters and C. yaquinae, recorded to 7,012 m (23,005 ft), is the only member in the family known from the hadal zone.
Trachydoras is a genus of fish in the family Doradidae native to South America.
Halieutopsis is a fish genus in the family Ogcocephalidae.
Coelophrys is a genus of fishes in the family Ogcocephalidae, one of the families of anglerfishes. They are distributed in the western Pacific Ocean and the Indian Ocean.
Guentherus is a genus of jellynose fishes, belonging to the Ateleopodidae family, with two recognized species:
Nudiantennarius is a monospecific genus of marine ray-finned fish belonging to the family Antennariidae, the frogfishes. The only species in the genus is Nudiantennarius subteres, the deepwater frogfish. This fish is found in the Western Pacific Ocean.
Cottus microstomus is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in Eastern Europe and is widespread in the Dniester drainage, Odra and Vistula drainages, most likely extending further east to the Gulf of Finland. It is part of the wider European Cottus gobio complex, and possibly makes hybrid zones with Cottus gobio and Cottus koshewnikowi. It is a demersal fish, up to 10.1 cm long.
Cheilodipterus is a genus of fishes in the family Apogonidae, the cardinalfishes. They are native to the Indian Ocean and the western Pacific Ocean.
Jaydia is a genus of fishes in the family Apogonidae native to the western Pacific Ocean.
Squalus montalbani, the Philippine spurdog or Indonesian greeneye spurdog, is a relatively large species of dogfish shark native to waters off the coast of Australia, the Philippines, and Indonesia. The species was identified in 1912 from a specimen caught off the coast of Luzon Island, and has been both bycatch and a targeted species in fisheries since. Its taxonomy is complex, having been renamed in 1931, being misidentified as a type of shortspine spurdog, then being revived as a species in 2007.
The Celebes monkfish is a species of marine ray-finned fish belonging to the family Lophiidae, the goose fishes, monkfishes or anglers. This species is found in the Indo-Pacific.
