Percilia irwini is a species of perch-like fish in the family Perciliidae found only in the Malleco and Bio-Bio River basins in Chile. [2]
Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Herring are forage fish, mostly belonging to the family Clupeidae.
The bull trout is a char of the family Salmonidae native to northwestern North America. Historically, S. confluentus has been known as the "Dolly Varden", but was reclassified as a separate species in 1980. Bull trout are listed as a threatened species under the U.S. Endangered Species Act (1998) and as vulnerable on the IUCN Red List of Threatened Species.
The Ganges shark is a critically endangered species of requiem shark found in the Ganges River and the Brahmaputra River of Bangladesh and India. It is often confused with the more common bull shark, which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark. Unlike bull sharks, which need to migrate to salt water to reproduce, species in the genus Glyphis are true river sharks. The genus is currently considered to contain three recent species; genetic evidence has shown that both the Borneo river shark and Irrawaddy river shark should be regarded as synonyms of the Ganges shark, expanding the range of the species to Pakistan, Myanmar, Borneo, and Java. The species remains poorly known and very rare.
The Gila trout is a species of salmonid, related to the rainbow, native to the Southwest United States. Prior to 2006 the Gila trout was federally listed as endangered. In July 2006, after much work by the Game and Fish departments in New Mexico and Arizona, the US Forest Service and the US Fish and Wildlife Service, the Gila trout was down-listed to threatened, with a special provision called a "4d rule" that will allow limited sport fishing – for the first time in nearly half a century. This possibility is distinct: there may be no one alive today that has legally angled a pure Gila trout from its native waters. By the time the Gila trout was closed to fishing in the 1950s, its numbers and range were so depleted and so reduced this copper-colored trout simply wasn't very accessible to anglers. As of 2011 there is fishing in both states for this fish.
The term billfish refers to a group of predatory fish characterised by prominent bills, or rostra, and by their large size; some are longer than 4 m (13 ft). Billfish include sailfish and marlin, which make up the family Istiophoridae, and swordfish, sole member of the family Xiphiidae. They are apex predators which feed on a wide variety of smaller fish, crustaceans, and cephalopods. These two families are sometimes classified as belonging to the order Istiophoriformes, a group with origins in the Late Cretaceous around 71 million years ago with the two families diverging from one and another in the Late Miocene around 15 million years ago. However, they are also classified as being closely related to the mackerels and tuna within the suborder Scombroidei of the order Perciformes. However, the 5th edition of the Fishes of the World does recognise the Istiophoriformes as a valid order, albeit including the Sphyraenidae, the barracudas.
The Pedder galaxias is an Australian freshwater fish. It is considered to be extinct in the wild since 2005 by the EPBC Act, and was originally found only in Lake Pedder in Tasmania.
Megalagrion is a genus of damselflies in the family Coenagrionidae It contains approximately 26 species, all of which are endemic to Hawaiʻi.
The Monito gecko is a lizard, a species of gecko endemic to the island of Monito, in the archipelago of Puerto Rico.
Irwin's turtle is a rare species of freshwater turtle in the family Chelidae. The species is endemic to Australia, originating from the lower region of the Burdekin River area.
Percilia gillissi, known as carmelita in Spanish, is a species of perch-like fish in the family Perciliidae found only in central and southern Chile. In Chile it is distributed from the Aconcagua Valley at a latitude of 32°S to the Los Lagos Region at 41°S where it is found in the cool temperatures, high oxygen levels, and fast, turbulent, swift flows of the rithron zone where it feeds on benthic invertebrates. They spawn in the southern spring and summer, starting in October with many juveniles being recorded in mid summer. Most of the juveniles attain maturity before the next summer. It attains a maximum total length of 9 centimetres (3.5 in).
Percilia is a genus of perch-like fish in the monogeneric family Perciliidae.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.
Fuxian Lake stretches out through Chengjiang, Jiangchuan and Huaning Counties in Yunnan Province, spanning an area of 212 square kilometers. The lake is ranked third-largest in Yunnan, after Dian Lake and Erhai Lake. Also the deepest lake in Yunnan, it is 155 meters deep at its greatest depth. It is also the third-deepest fresh water lake in China, after Tianchi and Kanas Lake.
Diplomystes nahuelbutaensis is a species of velvet catfish endemic to Chile where it occurs in the Bío-Bío River basin and in the Loncomilla River. It grows to a length of 26.0 centimetres (10.2 in) TL and is a component of local commercial fisheries as well as being a gamefish.
Trypanosoma irwini is a blood parasite of koalas. First discovered in 2009 by Linda M. McInnes and her peers, it was named in honor of Steve Irwin, "The Crocodile Hunter". The study done by McInnes et al. was the first to describe a Trypanosoma species from koalas.
Zenarchopteridae, the viviparous halfbeaks, is a family in the order Beloniformes. The Zenarchopteridae exhibit strong sexual dimorphism, practicing internal fertilisation, and in some cases ovoviviparous or viviparous. The members in the family are mainly found in fresh and brackish water of tropical Asia and New Guinea, but the genus Zenarchopterus also includes marine species from the Indo-Pacific. Several, such as the wrestling halfbeak, have become commonly traded aquarium fish.
The disparate angelshark is a species of angelshark. It occurs at depths down to 164 m in the Gulf of Mexico and reaches a length of 49 cm (19 in). Heteroptera in its name refers to the difference in size, shape and area of the two dorsal fins. Disparate angelsharks have the typical angel shark body form that is broadly flattened with large pectoral/pelvic fins and eyes and spiracles on the top of their heads. Their common and species name comes from them having dorsal fins of very different sizes, shapes, and areas compared to other angel sharks.
