Chinchillas have been exploited by humans for centuries. Commercial hunting of short-tailed chinchillas for fur began in 1828 in Chile, leading to an increased demand in Europe and the United States. As the demand for chinchilla pelts rose, the species number declined, leading to the species' apparent extinction in 1917.
Both species of chinchilla are currently listed as Endangered by the IUCN Red List of Threatened Species due to a severe population loss approximated at a 90% global population loss since 2001. [1] The severe population decline has been caused by chinchilla hunting by humans.
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 species include a fruit bat, two species of fish, eight types of mussels and 10 types of birds.
Endangered (EN) – very high risk of extinction in the wild, meets any of criteria A to E for Endangered. Vulnerable (VU) – meets one of the 5 Red List criteria and thus considered to be at high risk of unnatural (human-caused) extinction without further human intervention. Near Threatened (NT) – close to being endangered in the near future.

For example, a study found that 36% of purported mammalian extinction had been resolved, while the rest either had validity issues (insufficient evidence) or had been rediscovered. [3] As of June 2023, the IUCN listed 233 mammalian species as critically endangered, while 27% of all mammalian species were threatened with extinction. [4]
Enacted 50 years ago on Dec. 28, 1973, this legislation has played a pivotal role in preserving and protecting hundreds of species.
