How many baby Yellow-tailed woolly monkeys are in a litter?
A Yellow-tailed woolly monkey (Lagothrix flavicauda) usually gives birth to around 1 babies.
Each of those little ones spend around 224 days as a fetus before they are released into the wild. Upon birth, they weight 196 grams (0.43 lbs) and measure 8.5 cm (0′ 4″). They are a member of the Cebidae family (genus: Lagothrix). An adult Yellow-tailed woolly monkey grows up to a size of 55.1 cm (1′ 10″).
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 yellow-tailed woolly monkey (Oreonax flavicauda) is a New World monkey endemic to Peru. It is a rare primate species found only in the Peruvian Andes, in the departments of Amazonas and San Martin, as well as bordering areas of La Libertad, Huánuco, and Loreto. The yellow-tailed woolly monkey was at first classified in the genus Lagothrix along with other woolly monkeys, but due to debatable primary sources, they have been placed in Oreonax. Oreonax has been proposed to be a subgenus of Lagothrix, but others have regarded it as a full genus. A recent extensive study suggests that the yellow-tailed woolly monkey may indeed be in Lagothrix.
