The hammerhead sharks are a group of sharks that form the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a cephalofoil. Most hammerhead species are placed in the genus Sphyrna, while the winghead shark is placed in its own genus, Eusphyra. Many different, but not necessarily mutually exclusive, functions have been postulated for the cephalofoil, including sensory reception, manoeuvering, and prey manipulation. The cephalofoil gives the shark superior binocular vision and depth perception.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Chinchillas are either of two species of crepuscular rodents of the parvorder Caviomorpha. They are slightly larger and more robust than ground squirrels, and are native to the Andes mountains in South America. They live in colonies called "herds" at high elevations up to 4,270 m (14,000 ft). Historically, chinchillas lived in an area that included parts of Bolivia, Peru and Chile, but today, colonies in the wild are known only in Chile. Along with their relatives, viscachas, they make up the family Chinchillidae. They are also related to the chinchilla rat.
Maui Nui is a modern geologists' name given to a prehistoric Hawaiian island and the corresponding modern biogeographic region. Maui Nui is composed of four modern islands: Maui, Molokaʻi, Lānaʻi, and Kahoʻolawe. Administratively, the four modern islands comprise Maui County. Long after the breakup of Maui Nui, the four modern islands retained plant and animal life similar to each other. Thus, Maui Nui is not only a prehistoric island but also a modern biogeographic region.
Dalbergia melanoxylon is a flowering plant in the family Fabaceae, native to seasonally dry regions of Africa from Senegal east to Eritrea and south to the north-eastern parts of South Africa. The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments and fine furniture. Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species' low germination rates.
Meles is a genus of badgers containing four living species known as Eurasian badgers, the Japanese badger, Asian badger, Caucasian badger and European badger. In an older categorization, they were seen as a single species with three subspecies. There are also several extinct members of the genus. They are members of the subfamily Melinae of the weasel family, Mustelidae.
A conservation-dependent species is a species which has been categorized as "Conservation Dependent" ("LR/cd") by the International Union for Conservation of Nature (IUCN), as dependent on conservation efforts to prevent it from becoming endangered. A species that is reliant on the conservation attempts of humans is considered conservation dependent. Such species must be the focus of a continuing species-specific and/or habitat-specific conservation program, the cessation of which would result in the species qualifying for one of the threatened categories within a period of five years. The determination of status is constantly monitored and can change.
The blackmouth lanternshark is a species of dogfish shark within the family Etmopteridae. This species is part of a subgroup that includes one other species from within the family. It is known to inhabit the benthic zones of the Eastern Indian Ocean and the Arafura Sea. These sharks were first described in a 2002 issue of Cybium: International Journal of Ichthyology, and there is still much unknown about the species.
The Fuegian snipe also known as the cordilleran snipe, is a small stocky wader. It breeds in south-central Chile and Argentina south to Tierra del Fuego. It is mainly sedentary, but the Tierra del Fuego population winters in mainland Chile.
The lesser blind mole-rat is a species of rodent in the family Spalacidae. It is found in Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Hungary, North Macedonia, Romania, Serbia, Montenegro, Turkey and Ukraine.
Guibourtia ehie is an evergreen tree of the genus Guibourtia in the family Fabaceae, also known by the common names amazique, amazoué, hyedua, black hyedua, mozambique, ovangkol and shedua.
Stenodus nelma, known alternatively as the nelma, sheefish, siifish, inconnu or connie, is a commercial species of freshwater whitefish in the family Salmonidae. It is widespread in the Arctic rivers from the Kola Peninsula eastward across Siberia to the Anadyr River and also in the North American basins of the Yukon River and Mackenzie River.
Myxine is a genus of hagfish, from the Greek μυξῖνος.
The southern hagfish is a hagfish of the genus Myxine.
Sturnira angeli, also known as the Guadeloupe yellow-shouldered bat or Angel's yellow-shouldered bat, is a species of bat in the family Phyllostomidae. It is endemic to the Lesser Antilles. As of 2018 it is listed as near threatened by the IUCN.
The white-headed hagfish is a species of jawless fish of the family Myxinidae (hagfish).
Myxine circifrons, the whiteface hagfish, is a marine bathydemersal species of fish in the family Myxinidae. It is found off Southern California, Peru, and Chile and grows to 65 centimetres (26 in) total length.
Myxine affinis, the Patagonian hagfish, is a species of jawless fish in the family Myxinidae.
Myxine capensis, the Cape hagfish, is a species of jawless fish in the family Myxinidae.
