The short-tailed chinchilla (Chinchilla chinchilla) is a small rodent part of the Chinchillidae family and is classified as an endangered species by the IUCN.Originating in South America, the chinchilla is part of the genus Chinchilla, which is separated into two species: the long-tailed chinchilla and the short-tailed chinchilla.
The two living species of chinchilla are Chinchilla chinchilla [1] [2] (formerly known as Chinchilla brevicaudata) and Chinchilla lanigera. C. chinchilla has a shorter tail, a thicker neck and shoulders, and shorter ears than C. lanigera. The former species is currently facing extinction; the latter, though rare, can be found in the wild. [10]
A young wild Chilean chinchilla (2006) A domesticated chinchilla Chinchilla lanigera is smaller—wild animals have body lengths up to 260 mm (10 in)—has more rounded ears—45 mm (1.8 in) in length)—and a longer tail than C. chinchilla; its tail is usually about a third the size of its body—up to 130 mm (5.1 in) compared to 100 mm (3.9 in) in C. chinchilla.
The Machu Picchu arboreal chinchilla rat (Cuscomys oblativus) is a large species of South American chinchilla rats, known from skeletal remains found by members of the Peruvian Expedition of 1912. The animals were buried alongside people in ancient Inca tombs at Machu Picchu in Peru . [ 2 ]
The conservation status of the species has not been studied. Subclass: Theria. Infraclass: ... Long-tailed chinchilla, Chinchilla lanigera CR; Genus: Lagidium.
The forefeet have four toes while the hind feet have four small-clawed toes in Lagidium and Chinchilla but three large-clawed toes in Lagostomus, a digging species. Their dental formula is 1.0.1.3 1.0.1.3 and their incisors grow continually throughout their lives.
Lower risk/conservation dependent: Species which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued. LR/nt: Lower risk/near threatened: Species which are close to being classified as vulnerable but are not the subject of conservation programmes. LR/lc: Lower risk/least concern
Additionally 783 mammalian species (14% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
