Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic, or marine. Lutrinae is a branch of the Mustelidae family, which includes weasels, badgers, mink, and wolverines, among other animals.
Marlins are fish from the family Istiophoridae, which includes 11 species.
Galeocerdo is a genus of ground shark. Only a single species, G. cuvier, the tiger shark, is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a member of the requiem shark family Carcharhinidae, it is currently considered to be the only member of the family Galeocerdonidae. While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species much lower than previously assumed. The oldest fossils of the extant G. cuvier date to the middle Miocene.
Acanthuridae are a family of ray-finned fish which includes surgeonfishes, tangs, and unicornfishes. The family includes about 86 extant species of marine fish living in tropical seas, usually around coral reefs. Many of the species are brightly colored and popular in aquaria.
Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. The scientific name means "Aulopus-shaped", from Aulopus + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek aulós + Latin forma, the former in reference to the elongated shape of many aulopiforms.
Batrachoididae is the only family in the ray-finned fish order Batrachoidiformes. Members of this family are usually called toadfish or frogfish: both the English common name and scientific name refer to their toad-like appearance.
Lanternfish are small mesopelagic fish of the large family Myctophidae. One of two families in the order Myctophiformes, the Myctophidae are represented by 246 species in 33 genera, and are found in oceans worldwide. Lanternfishes are aptly named after their conspicuous use of bioluminescence. Their sister family, the Neoscopelidae, are much fewer in number but superficially very similar; at least one neoscopelid shares the common name "lanternfish": the large-scaled lantern fish, Neoscopelus macrolepidotus.
Codlets are a family, Bregmacerotidae, of cod-like fishes, containing the single genus Bregmaceros found in tropical and subtropical waters throughout the world. They are very small fishes and even the largest, B. lanceolatus, reaches only 11.5 cm (4.5 in) in length.
The brownspotted grouper, also known as the brown spotted reef cod, brown-spotted rockcod, coral grouper or honeycomb cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has an Indo-Pacific distribution but in the northern Indian Ocean this distribution is discontinuous. It forms part of a species complex with two closely related species in the genus Epinephelus.
The blacktip grouper, also known as the redbanded grouper, blacktipped cod, black-tipped rockcod, footballer cod, red-barred cod, red-barred rockcod, scarlet rock-cod or weathered rock-cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the tropical Indo-Pacific region. It is the type species of the genus Epinephelus.
The northern wolffish, also known as the blue sea cat or jelly cat, is a species of marine ray-finned fish belonging to the family Anarhichadidae, the wolf fishes. This species is found in the North Atlantic Ocean and Arctic Ocean.
Scomber is a genus of ray-finned fish in the family Scombridae living in the open ocean found in Atlantic, Indian and Pacific Ocean. The genus Scomber and the genus Rastrelliger comprise the tribe Scombrini, known as the "true mackerels". These fishes have an elongated body, highly streamlined, muscular and agile. The eyes are large, the head is elongated, with a big mouth provided with teeth. They have two triangular dorsal fins, with some stabilizing fins along the caudal peduncle. The basic color is blue-green with a silvery white belly and a darker back, usually black mottled.
Caranx is a genus of tropical to subtropical marine fishes in the jack family Carangidae, commonly known as jacks, trevallies and kingfishes. They are moderate- to large-sized, deep-bodied fishes which are distinguished from other carangid genera by specific gill raker, fin ray and dentition characteristics. The genus is represented in the Pacific, Indian and Atlantic Oceans, inhabiting both inshore and offshore regions, ranging from estuaries and bays to deep reefs and offshore islands. All species are powerful predators, taking a variety of fish, crustaceans and cephalopods, while they in turn are prey to larger pelagic fishes and sharks. A number of fish in the genus have a reputation as powerful gamefish and are highly sought by anglers. They often make up high amounts of the catch in various fisheries, but are generally considered poor to fair table fishes.
Amphiperca is an extinct genus of freshwater percomorph ray-finned fish that lived from the early to middle Eocene of Europe. It has one known species, A. multiformis, known from the famous Messel Pit of Germany. Indeterminate remains are known from concurrent formations in Occitanie, France. It was a predatory fish that is known to have fed on Thaumaturus and Rhenanoperca.
Aglyptorhynchus is an extinct genus of prehistoric marine billfish that was distributed worldwide from the early Eocene to the early Miocene. Fossils are primarily known from the Northern Hemisphere, but one species is also known to have inhabited the waters off New Zealand.
Lateolabrax is a genus of commercially important ray-finned fishes known as the Asian seabasses. It is the only genus in the family Lateolabracidae. This genus is native to the coastal waters of the western Pacific Ocean. This genus has also been included in family Moronidae and may be nested within the Polyprionidae.
Rypticus is a genus of marine ray-finned fish, related to the groupers and classified within the subfamily Epinephelinae of the family Serranidae. It is one of several genera of soapfishes. These fish live in the Atlantic and eastern Pacific Oceans in tropical and warmer temperate zones.
Giganthias is a small genus of marine ray-finned fish belonging to the Anthiinae subfamily, which is part of the family Serranidae. the groupers and sea basses. It contains two species from Japan, Taiwan, and Indonesia.
James Erwin Böhlke (1930–1982) was an American ichthyologist. From 1954 to 1982, he was curator of the Department of Ichthyology at the Academy of Natural Sciences of Philadelphia.
The ara, otherwise known as the saw-edged perch or the Dageumbari (다금바리) is a species of marine ray-finned fish from the monospecific genus Niphon which is in the monotypic tribe of the Niphonini which is part of the subfamily Epinephelinae of the family Serranidae, the groupers and sea basses. It is found in the Western Pacific Ocean from Japan south to the Philippines where it inhabits rock reefs and inshore waters with rocky sea beds, This species can grow up to 1 metre (3.3 ft) in total length. The tribe Niphonini is the sister to the other four tribes of Epinephelinae and it has been posited that it represents a basal lineage within this subfamily. The ara was first formally described in 1828 by Georges Cuvier in the Histoire naturelle des poissons which he co-authored with Achille Valenciennes, the type locality was given as the Sea of Japan.
