Extinct In Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: *Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) *Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) *Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) *Franklinia (last seen in 1803, listed extinct in the wild since 1998) *Golden skiffia (listed extinct in the wild since 1996) *Guam kingfisher (listed extinct in the wild since 1986) *Hawaiian crow or ʻalalā (last seen in 2002, li ...

Corvus Hawaiiensis FWS
''Corvus'' is a widely distributed genus of medium-sized to large birds in the family Corvidae. It includes species commonly known as crows, ravens and rooks. The species commonly encountered in Europe are the carrion crow, the hooded crow, the common raven and the rook; those discovered later were named "crow" or "raven" chiefly on the basis of their size, crows generally being smaller. The genus name is Latin for "crow". The 45 or so members of this genus occur on all temperate continents except South America, and several islands. The ''Corvus'' genus makes up a third of the species in the family Corvidae. The members appear to have evolved in Asia from the corvid stock, which had evolved in Australia. The collective name for a group of crows is a "flock" or a "murder". Recent research has found some crow species capable of not only tool use, but also tool construction. Crows are now considered to be among the world's most intelligent animals with an encephalization quot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Crow
The Hawaiian crow or alalā (''Corvus hawaiiensis'') is a species of bird in the crow family, Corvidae, that is currently extinct in the wild, though reintroduction programs are underway. It is about the size of the carrion crow at in length, but with more rounded wings and a much thicker bill. It has soft, brownish-black plumage and long, bristly throat feathers; the feet, legs and bill are black. Today, the Hawaiian crow is considered the most endangered of the family Corvidae. They are recorded to have lived up to 18 years in the wild, and 28 years in captivity. Some Native Hawaiians consider the Hawaiian crow an ''aumakua'' ( family god). The species is known for strong flying ability and resourcefulness, and the reasons for its extirpation are not fully understood. It is thought that introduced diseases, such as '' Toxoplasma gondii'', avian malaria (''Plasmodium relictum''), and fowlpox, were probably a significant factor in the species' decline., 16 MB file.

Wyoming Toad
The Wyoming toad or Baxter's toad (''Anaxyrus baxteri'') is an extremely rare amphibian that exists only in captivity and within Mortenson Lake National Wildlife Refuge in Wyoming in the United States. The Wyoming toad was listed as an endangered species in 1984, and listed as extinct in the wild since 1991. As with ferrets at the Tom Thorne and Beth Williams Wildlife Research Center at Sybille in Wheatland, Wyoming, the effort to save the Wyoming toad has been a cooperative effort among state and federal agencies and private landowners. The Wyoming toad was common from the 1950s through the early 1970s, but its distribution was limited to the Laramie Basin in Albany County. The population crashed around 1975 and was extremely low by 1980. The Wyoming toad was federally listed as endangered in January 1984. To prevent extinction, a captive-breeding program began in 1989 at the Thorne Williams Unit that produced enough offspring in its first few years to supply seven zoos, and in ...

South China Tiger
The South China tiger is a population of the '' Panthera tigris tigris'' subspecies that is native to southern China. The population mainly inhabited the Fujian, Guangdong, Hunan and Jiangxi provinces. It has been listed as Critically Endangered on the China's Red List of Vertebrates and is possibly extinct in the wild since no wild individual has been recorded since the late 1980s. In the late 1990s, continued survival was considered unlikely because of low prey density, widespread habitat degradation and fragmentation, and other human pressures. In the fur trade, it used to be called Amoy tiger. Taxonomy The scientific name ''Felis tigris'' var. ''amoyensis'' was proposed by Max Hilzheimer in 1905 who described five tiger skulls from Hankou in southern China that differed slightly in shape from Bengal tiger skulls. Analysis of South China tiger skulls showed that they differ in shape from tiger skulls of other regions. Because of this phenomenon the South China tiger ...

Socorro Isopod
''Thermosphaeroma thermophilum'' is a crustacean in the family Sphaeromatidae. It is commonly known as the Socorro isopod or Socorro sowbug. It was endemic to the thermal water oSedillo Spring This was located in Socorro County in the state of New Mexico, United States. Harriet Richardson first described the Socorro isopod in 1897. As of 2006, it resides in captive populations at the Socorro Isopod Propagation Facility (SIPF), Albuquerque Biological Park (ABP), the Minnesota Zoo, the New Mexico Department of Game and Fish Laboratory in Santa Fe, and by the Department of Biology at New Mexico Tech. It was reintroduced following a near-extinction incident in 1988. The wild population became extinct when a tree root burst the pipe and cut off water flow to the concrete pools. Description The body size of the Socorro isopod is sexually dimorphic, varying noticeably depending on gender. Males tend to reach 7.1 millimeters in length on average (4-13 millimeter range).

Chad
Chad (; ar, تشاد , ; french: Tchad, ), officially the Republic of Chad, '; ) is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the southwest, Nigeria to the southwest (at Lake Chad), and Niger to the west. Chad has a population of 16 million, of which 1.6 million live in the capital and largest city of N'Djamena. Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the second-largest wetland in Africa. Chad's official languages are Arabic and French. It is home to over 200 different ethnic and linguistic groups. Islam (55.1%) and Christianity (41.1%) are the main religions practiced in Chad. Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great number ...

Scimitar Oryx
The scimitar oryx (''Oryx dammah''), also known as the scimitar-horned oryx and the Sahara oryx, is a ''Oryx'' species that was once widespread across North Africa. In 2000, it was declared extinct in the wild on the IUCN Red List. A captive bred group was released into an acclimation enclosure within the Ouadi Rimé-Ouadi Achim Faunal Reserve in 2016, then reintroduced into the wild. An additional 21 individuals were released into the acclimation enclosure in 2017. The first ones to be relocated were released into the wild in 2016 and have adapted well to their surroundings. In 2017, another herd of 75 scimitar-horned oryxes arrived in an operation led by Chad's Ministry of Environment and Fisheries and the Sahara Conservation Fund. In 2021, 60 new calves were born, bringing the number in the wild to about 400. This particular oryx can survive for months or even years without drinking water. A grazing animal, it derives most of its daily moisture intake from plants. The sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Père David's Deer
The Père David's deer (''Elaphurus davidianus''), also known as the ''milu'' () or elaphure, is a species of deer native to the subtropical river valleys of China. It grazes mainly on grass and aquatic plants. It is the only extant member of the genus '' Elaphurus''. Some experts suggest demoting ''Elaphurus'' to a subgenus of ''Cervus''. Based on genetic comparisons, Père David's deer is closely related to Eld's deer. Père David's deer were hunted almost to extinction in their native China by the late 19th century, but a number were taken to zoos in France and Germany and the deer was bred successfully in captivity. In the early 20th century, the British nobleman and politician Herbrand Russell, 11th Duke of Bedford, acquired a few Père David's deer from the Berlin Zoo and built up a large herd on his estate at Woburn Abbey. In the 1980s, the duke's great-grandson Robin Russell, 14th Duke of Bedford, donated several dozen deer to the Chinese government for reintroduc ...

Panamanian Golden Frog
The Panamanian golden frog (''Atelopus zeteki''), also known as Cerro Campana stubfoot toad and other names, is a species of toad endemic to Panama. Panamanian golden frogs inhabit the streams along the mountainous slopes of the Cordilleran cloud forests of west-central Panama. While the IUCN lists it as Critically Endangered, it may in fact have been extinct in the wild since 2007. Individuals have been collected for breeding in captivity in a bid to preserve the species. The alternative common name, Zetek's golden frog, and the epithet ''zeteki'' both commemorate the entomologist James Zetek. Description Despite its common name, the Panamanian golden frog is a true toad, a member of the family Bufonidae. It was first described as a subspecies of ''Atelopus varius'', but is now classified as a separate species. The Panamanian golden frog is a national symbol and is considered to be one of the most beautiful frogs in Panama. The skin colour ranges from light yellow-green to b ...
