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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
The royal ground snake is a species of snake in the family Colubridae. The species is endemic to northern South America.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as Critically Endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.
The fawn-colored mouse is a species of rodent in the family Muridae. It is found in Cambodia, India, Indonesia, Laos, Myanmar, Nepal, Thailand, and Vietnam.
Bamboo partridges, sometimes called ridge partridges, are medium-sized non-migratory birds of the genus Bambusicola in the family Phasianidae.They have a wide native distribution throughout Asia. They were formerly grouped in the Perdicinae subfamily of the Phasianidae. However, molecular research suggests that partridges are not a distinct taxon within the family Phasianidae, but that some species are closer to the pheasants, while others are closer to the junglefowl. Phylogenetic evidence supports the bamboo partridges as being the sister genus to the junglefowl.
Boana semilineata is a species of frog in the family Hylidae that is endemic to Brazil. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist shrubland, freshwater lakes, freshwater marshes, intermittent freshwater marshes, pastureland, heavily degraded former forests, water storage areas, and ponds.
The gray-footed chipmunk is a terrestrial and forest-dwelling species of chipmunk and rodent in the family Sciuridae. It is endemic to New Mexico and in the Sierra Diablo and Guadalupe Mountains in the Trans-Pecos region of Texas in the United States. Its natural habitat are coniferous forests. First discovered in 1902, they are distinguished by the unique gray dorsal colouring on the hind feet, hence the common name. They demonstrate sexual dimorphism, and the female is larger than the male.
Opisthopatus roseus is a species of velvet worm in the Peripatopsidae family. As traditionally defined, this species is rose pink with 18 pairs of legs. Known as the pink velvet worm, it is found only in the Weza Forest, a Mistbelt Forest in South Africa.
Tropidophora semilineata was a species of land snail with a gill and an operculum, a terrestrial gastropod mollusk in the family Pomatiidae. This species was endemic to Mayotte. It is now extinct.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Enoploteuthis is a genus of squid in the family Enoploteuthidae. The species of Enoploteuthis are most easily recognised by having a larger tail when compared to the other genera in the Enoploteuthidae. The tail's size is emphasised by not having the fins extending along its sides. In related genera there is a narrow extension of the fins along the tail. Other characteristics include the presence of suckers on the distal portion of arms IV where there at no photophores present; the tentacular club has two rows of hooks and no marginal suckers; on the buccal crown there are typical chromatophores on the aboral surface but on the oral surface there may be some light skin pigmentation. They have 9-10 photophores on the eye and they have complex photophores in the skin. In the females the Spermatangia receptacles are at the posterior junction of muscles used to retract the funnel and the muscles which retract the head. Enoploteuthis differs from other genera of the Enoploteuthidae in having two rather than three types of photophores in its integument and these are on the ventral areas of the head, funnel and mantle. All species of Enoploteuthis which have been studied have the most complex type of photophoreand seems to be a distinctive characteristic of this genus. Enoploteuthis contains the largest species in the family, attaining a mantle length of 130mm.
Enoploteuthis leptura, the hooked enope squid, is a species of squid from the family Enoploteuthidae. It is the type species of the genus Enoploteuthis, which is in turn the type genus of the Enoploteuthidae.
Enoploteuthis jonesi is a species of squid from the family Enoploteuthidae. The species is gonochoric and can be found in the Pacific Ocean.
Enoploteuthis galaxias is a species of squid from the family Enoploteuthidae. The species has been observed off the coast of Tasmania.
Enoploteuthis obliqua is a species of squid from the family Enoploteuthidae. The species is rarely documented, but has been observed in the North Pacific Ocean.
Enoploteuthis chunii is a species of squid from the family Enoploteuthidae. They have been observed off the coast of Korea.
Enoploteuthis galaxias is a species of squid from the family Enoploteuthidae. The species has been observed in the North Pacific Ocean.
Enoploteuthis anapsis, also known as the starlit enope squid, is a species of squid from the family Enoploteuthidae. The species is gonochoric, and can be found in the Atlantic Ocean.
