How many baby White-footed tamarins are in a litter?
A White-footed tamarin (Saguinus leucopus) usually gives birth to around 2 babies.
Each of those little ones spend around 142 days as a fetus before they are released into the wild. Upon birth, they weight 43 grams (0.09 lbs) and measure 3.7 cm (0′ 2″). They are a member of the Callitrichidae family (genus: Saguinus). An adult White-footed tamarin grows up to a size of 24 cm (0′ 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 white-footed tamarin (Saguinus leucopus) is a tamarin species endemic to Colombia. It is a silvery brown colour with pale streaks and russet underparts, and is very similar in appearance to the cotton-top tamarin, from which it is separated by the Atrato River. It is thought that the two species diverged during the Pleistocene, at a time when a sea occupied the area between their present ranges. This tamarin is an arboreal species, living in small family groups in the canopy. Females give birth to one to three young after a gestation period of about 140 days. This species has a relatively small range and is under threat from destruction and fragmentation of the forest in which it lives and the International Union for Conservation of Nature has assessed its conservation status as “endangered”.
