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.

Branchinecta gigas, the giant fairy shrimp, is the largest species in the order, with a length of up to 10 centimetres (4 in), and Branchinecta brushi lives at the highest altitude of any crustacean, at 5,930 metres (19,460 ft), a record it shares with the copepod Boeckella palustris. A new genus, Archaebranchinecta was established in 2011 for two species previously placed in Branchinecta.

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.
