The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific. The family name Cyclopteridae derives from the Greek words κύκλος (kyklos), meaning "circle", and πτέρυξ (pteryx), meaning "wing" or "fin", in reference to the circle-shaped pectoral fins of most of the fish in this family.
Macroplata is an extinct genus of Early Jurassic rhomaleosaurid plesiosaur which grew up to 4.65 metres (15.3 ft) in length. Like other plesiosaurs, Macroplata probably lived on a diet of fish, using its sharp needle-like teeth to catch prey. Its shoulder bones were fairly large, indicating a powerful forward stroke for fast swimming. Macroplata also had a relatively long neck, twice the length of the skull, in contrast to pliosaurs. It is known from a nearly complete skeleton NHMUK PV R5488 from the Blue Lias Formation (Hettangian) of Harbury, Warwickshire, UK.
Asterophysus batrachus, the gulper catfish or ogre catfish, is a species of catfish of the family Auchenipteridae. It is native to the Rio Negro and Orinoco basins in Brazil, Colombia and Venezuela, where mostly found in slow-moving waters with many submerged structures. It is currently the only recognized species of the genus Asterophysus, but a specimen that possibly represents an undescribed species has been collected in Marajó.
Chrysochampsa is an extinct monospecific genus of caiman of the clade Brachychampsini. Fossils have been found from the Golden Valley Formation of North Dakota and date back to the Wasatchian regional North American faunal stage of the early Eocene. During this time North Dakota experienced the Early Eocene Climatic Optimum, creating lush forests, swamps and meandering rivers that were the home to at least four distinct crocodilians. Unlike the contemporary Ahdeskatanka, which was a small animal with crushing teeth, Chrysochampsa would have been a generalist and due to its size and lack of significant mammalian carnivores the apex predator of the region. The genus had been proposed to be synonymous with Allognathosuchus in 2004s, but this claim has since then been repeatedly refuted. A 2024 study has recovered it as an early branching member of the Caimaninae, forming a clade with Cretaceous forms such as Brachychampsa. Chrysochampsa is a monotypic genus, containing only the type species, Chrysochampsa mlynarskii.
Laganosuchus is an extinct genus of stomatosuchid crocodyliform. Fossils have been found from Niger and Morocco and date back to the Upper Cretaceous.
Cyclopteropsis is a genus of marine ray-finned fishes belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. These small lumpfishes are found in the North Pacific and Arctic Oceans.
Eumicrotremus is a genus of lumpfishes native to the northern oceans. The name for this genus comes from the Greek roots eu meaning "good", mikros meaning "small" or "little", and trema meaning "hole".
Lethotremus is a monospecific genus of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. This genus is found in the northern Pacific Ocean. Following a 2017 taxonomic review by Lee et al., the species Lethotremus awae was reclassified as a species of Eumicrotremus, leaving the genus monotypic with Lethotremus muticus as its only species. Also known as the docked snailfish, is a species of lumpfish native to the Northeast Pacific. It is known from the Bering Sea and the Aleutian Islands, where its range extends to Unimak Pass, and it occurs at a depth range of 58 to 330 m. It is a benthic species that reaches 11.5 cm in total length. It can be found on substrates of mud, rock, or gravel, and it is currently the only known species of Lethotremus, following a reclassification of the second described species in the genus as Eumicrotremus awae.
The Pacific spiny lumpsucker is a species of bony fish in the family Cyclopteridae.
Dongnanosuchus is an extinct monotypic genus of orientalosuchin crocodilian known from the middle to late Eocene Youganwo Formation of China. Like other members of Orientalosuchina, Dongnanosuchus was a comparably small-bodied animal with a short, rounded snout that shares characteristics with both early alligatoroids and crocodylids, rendering the precise placement of the clade uncertain. It contains a single species, Dongnanosuchus hsui, which lived during the latter part of the Eocene in what is now the Maoming Basin of China, which at the time featured subtropical forests and a prominent lake that would be the foundation of the local oil shale. This environment was shared by the tomistomine Maomingosuchus and similar cohabitation between Maomingosuchus and orientalosuchins is known from similar sites across East Asia.
The toad lumpsucker is a species of fish in the family Cyclopteridae that can be found in the Bering Sea and the Gulf of Alaska, where it occurs at depths of 69 to 170 metres. It is a demersal fish that reaches a maximum of 7.4 centimetres (2.9 in) in total length, making it a moderately sized member of Eumicrotremus.
Eumicrotremus andriashevi, also known as the pimpled lumpsucker, is a species of lumpfish native to the Arctic and North Pacific. In addition to the Arctic Ocean, it may be found in the Chukchi and Bering Seas, where it occurs at a depth range of 20 to 83 m. It is a small bottom-dwelling fish that reaches 4.8 cm in standard length.
Eumicrotremus spinosus, commonly known as the Atlantic spiny lumpsucker, is a species of lumpfish native to the Arctic and North Atlantic.
Eumicrotremus pacificus, sometimes known as the spotted lumpsucker or the balloon lumpfish, is a species of lumpfish native to the Northwest Pacific. It can be found in the Sea of Okhotsk, the Sea of Japan, the East China Sea, and the Pacific Ocean off Hokkaido and the Kuril Islands. It may be confused with the closely related Eumicrotremus orbis, which overlaps with E. pacificus in range, although E. pacificus is larger, reaching 20 cm (7.9 inches) TL. This fish is generally yellow to orange in color with small dark spots and its tubercles are usually smaller and less pronounced than E. orbis, giving it a less spiny appearance.
Proeumicrotrmus is a monospecific genus of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. The only species in the genus is Proeumicrotremus soldatovi, Soldatov's lumpsucker. This species is found in the Northwest Pacific. It is known from the Sea of Okhotsk, where it can be found at depths of 10 to 350 m. It reaches 26 cm (10 in) in total length, making it larger than average for a lumpfish. It was previously considered a species of Eumicrotremus until a morphology-based revision in 2020 concluded that it represents the only known species of a distinct genus.
Eumicrotremus tokranovi is a species of lumpfish native to the Northwest Pacific, and one of two species some authorities place in the genus Microancathus. It is known from the Kuril Islands. It is distinguished from the closely related E. fedorovi by a taller body and flatter and less developed bone plaques. FishBase does not recognize the genus Microancathus,. This species was described by the Russian ichthyologist Olga Stepanovna Voskoboinikova in 2015 in the proposed new genus, Microancathus and the reclassification of M. fedorovi in that genus. Catalog of Fishes does not recognize the new genus and classifies this species in Eumicrotremus. The specific name honors the ichthyologist Alexei Mikhailovich Tokranovof the Kamchatka Branch of the Pacific Institute of Geography and the Far East Branch of the Russian Academy of Sciences.
Eardasaurus is a genus of thalassophonean pliosaurid from the middle Jurassic Oxford Clay Formation. The animal would have measured over 4.7 m (15 ft) long and possessed a high amount of teeth relative to other pliosaurs. Its teeth show distinct ridges formed by the tooth enamel, some of which are very pronounced and similar to carinae, giving the teeth a cutting edge.
The blackspotted gurnard, also known as the half-spotted gurnard, is a species of marine ray-finned fish belonging to the family Triglidae, the gurnards and sea robins. It is found in the Indo-Pacific region.
Cyclopteroidea is a superfamily of ray-finned fishes within the order Scorpaeniformes. The superfamily comprises 2 families, the Cyclopteridae, the lumpsuckers, of the cool northern seas and the widespread Liparidae, the snailfishes. A common feature shared by these families is that they typically have the pelvic fins modified to form a disc shaped sucker.
Eumicrotremus fedorovi is a species of marine ray-finned fish belonging to the family Cyclopteridae, the lumpfishes or lumpsuckers. This species is found in the northwestern Pacific Ocean around the Kuril Islands. It is a demersal fish that occurs at a depth range of 115 to 370 m. This species was first formally described in 1991 by Sergey Anatolyevich Mandritsa with its type locality given as the Rikord Strait. The specific name honours the Russian zoologist Vladimir Vladimirovich Fedorov who studied the holotype and suggested that it represented a new species.
