How many baby Short-tailed chinchillas are in a litter?
A Short-tailed chinchilla (Chinchilla brevicaudata) usually gives birth to around 2 babies.With 2 litters per year, that sums up to a yearly offspring of 4 babies.
Each of those little ones spend around 110 days as a fetus before they are released into the wild. Upon birth, they weight 14 grams (0.03 lbs) and measure 7.6 cm (0′ 3″). They are a member of the Chinchillidae family (genus: Chinchilla). An adult Short-tailed chinchilla grows up to a size of 30.5 cm (1′ 1″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
The short-tailed chinchilla (Chinchilla chinchilla; formerly C. brevicaudata)—also called the Bolivian, Peruvian, or royal chinchilla—is an endangered species of South American rodent, and one of two species in the genus Chinchilla. Their original native range extended throughout the Andes Mountains of Argentina, Chile, Peru, and Bolivia. These animals were exploited for their luxurious fur, causing their numbers in the wild to dwindle. The other species of chinchilla is also endangered; C. lanigera, or the long-tailed chinchilla, is the wild ancestor of the domestic chinchilla, which is commonly raised as a pocket pet throughout the world.
