Odontesthe mauleanum is a species of fish in the family Atherinopsidae. It is endemic to Chile.
The guanay cormorant or guanay shag is a member of the cormorant family found on the Pacific coast of Peru and northern Chile. After breeding it spreads south to southern parts of Chile and north to Ecuador, and has also been recorded as far north as Panama and Colombia – probably a result of mass dispersal due to food shortage in El Niño years. Its major habitats include shallow seawater and rocky shores.
The Titicaca grebe, also known as the Titicaca flightless grebe or short-winged grebe, is a grebe found on the altiplano of Peru and Bolivia. As its name implies, its main population occurs on Lake Titicaca. Lake Uru Uru and Poopó, the Rio Desaguadero, and small lakes that connect to Lake Titicaca in wet years, serve as "spillovers" territory. In the past, the population was larger and several of these lakes – such as Lakes Umayo and Arapa – apparently had and may still have permanent large colonies. It is sometimes placed in Podiceps or a monotypic genus Centropelma. Its local name is zampullín del Titicaca.
The Titicaca orestias, Lake Titicaca orestias, or Lake Titicaca flat-headed fish, also known by its native name amanto, is a likely extinct freshwater killifish from Lake Titicaca in South America. It belongs in the pupfish genus Orestias, endemic to lakes, rivers and streams in the Andean highlands. With a total length of up to 27 cm (10.6 in), it was the largest member in that genus. In the hope that an undiscovered population remains, it is listed as Data Deficient by the IUCN. Despite its common name, it is not the only Orestias from Lake Titicaca.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
The Somali hedgehog is a species of mammal in the family Erinaceidae. It is endemic to Somalia and Somaliland. The Somali hedgehog is nocturnal.
The pale gray shrew is a species of mammal in the family Soricidae. It is endemic to Pakistan and is distributed in the Shigar valley and the western edge of Deosai.
Portenko's shrew is a species of mammal in the family Soricidae that is endemic to Russia.
The long-tailed mountain shrew is a species of mammal in the family Soricidae. It is found in China, Myanmar, Nepal, and Vietnam.
The Lowe's shrew is a species of mammal in the family Soricidae. It is found in China, Myanmar, Thailand, and Vietnam.
Odontesthes gracilis is a species of fish in the family Atherinidae. It is endemic to the Juan Fernandez Islands off Chile. It occurs around the mouths of caves, in inlets and around piers. This is a species which can be found in freshwater, brackish and marine waters. This species was described as Chirostoma gracile in 1898 by Franz Steindachner with the type locality given as Más a Tierra.
Speleoperipatus is a monospecific genus of velvet worm in the Peripatidae family, containing the single species Speleoperipatus spelaeus. This species is a pale greenish yellow, almost white, with 22 or 23 pairs of legs and no eyes. Specimens range from 27 mm to 34 mm in length. The minimum number of leg pairs found in this species (22) is also the minimum number found in the neotropical Peripatidae. This velvet worm is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Odontesthes regia is a fish belonging to the family Atherinopsidae, commonly referred to in English as Chilean silverside, Peruvian silverside or sea silverside, and in Spanish as pejerrey or pejerrey de mar.
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Odontesthes is a genus of Neotropical silversides. They are found in fresh, brackish and salt water habitats in the southern half of South America, as well as the offshore Juan Fernández and Falkland Islands. Additionally, O. bonariensis has been introduced to other continents.
Odontesthes bonariensis is a species of Neotropical silverside, an euryhaline fish native to fresh, brackish and salt water in south-central and southeastern South America, but also introduced elsewhere. It is often known by the common name Argentinian silverside or pejerrey, but it is not the only species of silverside in Argentina and pejerrey is also used for many other silversides. It is a commercially important species and the target of major fisheries.
Atherinopsinae is a subfamily of the Neotropical silversides, part of the family Atherinopsidae. This subfamily is made up of two tribes, six genera and around 30 species. They are found in the eastern Pacific and south-western Atlantic and the subfamily contains marine, brackish and freshwater species.
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
