Kurtus is a genus of percomorph fishes, called the nurseryfishes, forehead brooders, or incubator fish, native to fresh, brackish and coastal marine waters ranging from India, through southeast Asia, to New Guinea and northern Australia. Kurtus is currently the only known genus in the family Kurtidae, one of two families in the order Kurtiformes. They are famous for carrying their egg clusters on hooks protruding from the forehead (supraoccipital) of the males, although this only has been documented in K. gulliveri and available evidence strongly suggests this is not done by K. indicus. Females do not have a hook.
Uaru fernandezyepezi is a species of cichlid native to South America where it is found in rivers of the Orinoco basin. This species can reach a length of 24 centimetres (9.4 in) TL. It is also found in the aquarium trade.
The Olympic mudminnow is a fish native to the western lowlands of Washington: the Chehalis River basin, Deschutes River basin, and some Olympic Peninsula basins. It grows to 8 cm in length, and is Washington's only known endemic freshwater fish species. Although they strongly resemble killifish, mudminnows are more closely related to pike and muskellunge.
Livingston's bulldog Marcusenius livingstonii is a species of ray-finned fish in the family Mormyridae. It is found in Malawi, Mozambique, and Tanzania. Its natural habitats are rivers, intermittent rivers, and freshwater lakes. It is threatened by habitat loss.
Acheilognathus deignani is a species of freshwater ray-finned fish in the genus Acheilognathus. It is endemic to northern Vietnam in the Mekong River. It grows to a maximum length of 5.2 cm.
The butterfly barb is a species of cyprinid fish in the genus Enteromius.
Protoxotes lorentzi is a tropical freshwater fish found in streams and swamps of the Northern Territory of Australia, Irian Jaya (Indonesia), and Papua New Guinea. It was first named by Weber in 1910, and is commonly known as the primitive archerfish or Lorentz's archerfish.
Cyprinella whipplei, the steelcolor shiner, is a freshwater fish species found in North America. It is common throughout the Mississippi River basin and in the Black Warrior River system in Alabama.
The blackspotted stickleback is species of ray-finned fish belonging to the family Gasterosteidae, the sticklebacks. This fish is found in the western Atlantic from the coasts of Newfoundland (Canada) to Massachusetts. This is a benthopelagic species of marine and brackish waters, rarely entering freshwater, which remains near the shore. It is frequently associated with floating vegetation. The male builds a nest, in which the females deposit eggs and the male guards and aerates them. It is a small fish which reaches a maximum published total length of 7.6 cm (3.0 in), although 3.5 cm (1.4 in) is more typical. The specific name honors Richard H. Wheatland who was the Cabinet Keeper, for the Essex County Natural History Society of Salem, Massachusetts and who collected type of this species in 1859.
Marcusenius thomasi is a species of ray-finned fish in the family Mormyridae. It is found in Guinea, Guinea-Bassau, Liberia, and Sierre Leone. Its natural habitats are rivers, intermittent rivers, and freshwater lakes. It is threatened by Mining and deforestation.
Gerald Robert "Gerry" Allen is an American-born Australian ichthyologist. His career began in 1963, when he spent a semester at the University of Hawaii, where he also received a PhD in marine zoology in 1971. In 1972, Allen wrote his doctoral thesis on the systematics and biology of the anemone fish.
Kurtus indicus, the Indian humphead, is a species of fish in the family Kurtidae native to fresh, brackish, and marine waters of the coastal regions of southern Asia from India to southeast China and Indonesia. It resembles the closely related K. gulliveri, but is far smaller, only reaching a length of 12.6 cm (5 in). Although it has been suggested that the male carries the egg cluster on a hook protruding from the forehead, available evidence strongly suggests this is not the case in K. indicus: Out of several thousand examined, none carried eggs in this manner and the male's hook is likely also too small. The female lacks the hook entirely. It is of minor importance to local commercial fisheries.
Nematolebias whitei, the Rio pearlfish, is a species of killifish from the family Rivulidae. It is endemic to Brazil where it is found in the Laguna de Araruama basin, Das Ostras River basin and in coastal plains in the vicinity of the mouth of São João River in Rio de Janeiro State. It was introduced to California in the 20th Century but they did not become established there.
Cottus rhenanus is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in France, Belgium, Germany, Luxembourg, and the Netherlands. It inhabits the Rhine and Meuse river drainages. It reaches a maximum length of 10.0 cm. It prefers streams with clear, cool, moderate to swift water and stone substrate. Here, it mostly occurs in the shallow parts of streams. This species was described as a separate species from the European bullhead in 2005 by Jörg Freyhof, Maurice Kottelat and Arne W. Nolte. The specific name rhenatus means belonging to Rhenus, the Latin name of the River Rhine.
Cottus perifretum, the bullhead or miller’s thumb, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found on both sides of the English Channel, native to Great Britain. It also inhabits Atlantic drainages from the Garonne River to the Scheldt in France and Belgium, and the Moselle and Sieg in Germany. It is considered invasive in the Rhine drainage in Germany and the Netherlands. This invasive population in the Rhine is an intermediate between this species and Cottus rhenanus. Although this species is native to England and Wales it is considered to be a non-native invasive species in Scotland.
Cottus volki is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is endemic to Russia where it is found along the continental coasts of the Sea of Japan but not on the coasts of Peter the Great Bay. It reaches a maximum length of 13 cm (5.1 in). It was previously considered a subspecies of the alpine bullhead. and this species was first formally described in 1933 by the Russian ichthyologist Anatoly Yakovlevich Taranetz as Cottus poecilopus volki with its type locality given as the Suchan River to Takema River on western coast of the Sea of Japan in Primorye. Taranetz did not identify the person honoured in the specific name but it is thought most likely to be his friend Alexander Maksimovich Volk, like Taranetz, Volk was killed in action during World War 2.
Copella arnoldi, commonly known as the splash tetra or the splashing tetra, is a species of tropical freshwater fish belonging to the family Lebiasinidae. It is native to South America.
Helen K. Larson is an ichthyologist who specialises in the fishes of the Indo-Pacific.
