Speke's gazelle is the smallest of the gazelle species. It is confined to the Horn of Africa, where it inhabits stony brush, grass steppes, and semi deserts. This species has been sometimes regarded as a subspecies of the Dorcas gazelle, though this is now widely disregarded. Severe habitat fragmentation means it is now impossible to assess the natural migratory or nomadic patterns of G. spekei. Its numbers are under threat, and despite an increase in population, the IUCN in 2007 announced its status had changed from vulnerable to endangered. A captive population is maintained, and the wild population exists in the lower tens of thousands. As of 2008, this gazelle is classified as endangered under the IUCN Red List.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or conservation dependent.
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.
The Himalayan mole or short-tailed mole is a species of mammal in the family Talpidae.
The small-toothed mole is a species of mammal in the family Talpidae. It is found in Di Linh, in southern Vietnam, and Rakho near the border of Vietnam and China, and in southern Yunnan, China, near the Vietnamese border. It is likely that it has a broader distribution, especially in places between the currently known locations.
Eodiaptomus lumholtzi is a species of copepod endemic to Australia. It is one of only two species in the family Diaptomidae to occur in Australia, the other being Tropodiaptomus australis. It is listed as a vulnerable species on the IUCN Red List.
Tropodiaptomus is a genus of copepods in the family Diaptomidae. It includes the following species, many of which are narrow endemics and are included on the IUCN Red List :

Tropodiaptomus stuhlmanni is a species of calanoid copepod in the family Diaptomidae.
Tropodiaptomus worthingtoni is a species of calanoid copepod in the family Diaptomidae.
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 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 (CR). In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered (EN) worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
