It is hard to guess what a Geoffroy’s tamarin weights. But we have the answer:
An adult Geoffroy’s tamarin (Saguinus geoffroyi) on average weights 493 grams (1.09 lbs).
The Geoffroy’s tamarin is from the family Callitrichidae (genus: Saguinus). It is usually born with about 48 grams (0.11 lbs). When reaching adult age, they grow up to 23.9 cm (0′ 10″). Usually, Geoffroy’s tamarins have 2 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
Geoffroy’s tamarin (Saguinus geoffroyi), also known as the Panamanian, red-crested or rufous-naped tamarin, is a tamarin, a type of small monkey, found in Panama and Colombia. It is predominantly black and white, with a reddish nape. Diurnal, Geoffroy’s tamarin spends most of its time in trees, but does come down to the ground occasionally. It lives in groups that most often number between three and five individuals, and generally include one or more adults of each sex. It eats a variety of foods, including insects, exudates, fruits and other plant parts. Insects and fruits account for the majority of its diet, but exudates are also important. But since its teeth are not adapted for gouging trees to get to the sap, it can only eat exudates when they are easily available.Although a variety of reproductive methods are used, the most common is for a single adult female in the group to be reproductively active and to mate with multiple adult males in the group. After a gestation period of about 145 days, she gives birth to either a single infant or twins. Males contribute significantly to care of the infants. Sexual maturity is reached at about 2 years, and it can live up to 13 years. Geoffroy’s tamarin is classified as being of “least concern” by the IUCN.
