Marmosets (Callithrix jacchus) are New World monkeys. They originally lived in the rainforest of the Northeastern coast of Brazil. They are very small monkeys with relatively long tails. Males and females are of similar size. Their body being around 7-10 inches and weighing nearly 16 ounces. The fur of the marmoset is multicolored, being sprinkled with brown, grey, and yellow. Common marmosets have white ear tufts, while Penicillatas have black ear tufts and Geoffreys have a mostly white fur around their faces. A marmoset's face has black across the nose area and a white blaze on the forehead. The coats of infants lack ear tufts and have grey fur over their head and neck. Marmosets have claw-like nails on most of their fingers. Only their big toes have the flat nails. They can hang on to trees vertically and leap between them, as well as run across branches.


Their life spans are about 12 to 18 years, with maturity being about a year. The age of reproduction is a little over a year. They are usually pregnant for 144 days or around 5 months. They usually have 2 offspring but often 3.

Babies are born with a brown greyish coat and develop their white ear tufts and forehead blaze as they age.

Cotton Top Tamarins are easily recognizable due to the mane of beautiful long white fur that flows over their head which comes to a Mohawk just about their eyes. The rest of their face is black skin with banding of white or grey above their eyes. These small tamarins have white bodies, arms, and legs with blackish backs. Their body is around 10 inches in length with tails another 12-16 inches. They weigh about 1 pound. In the wild, their lifespan may be as little as 13 years, while in captivity this can extend out to 23 years. Today Cotton Tops are classified critically endangered and one of the rarest primates in the world. The main reason for the severe decline in the Cotton Top Tamarin population is that they have lost more than 95% of their natural habitat to deforestation. It is estimated to be around 2,000 mature Cotton Tops left in the wild. For this reason, Cotton Tops must remain in the state they were born and can not be sold to another state.

Red Handed Tamarins



Red Handed Tamarins are new world monkeys meaning they are found in Central and South America. They are named for the reddish hair on their hands and feet, while the rest of their body is black with red underneath. It almost looks like they are wearing red gloves. They measure about 12 inches tall and weighing around a pound. Life expectancy is about 15 years or more in captivity. These tamarins are known to have a calm demeanor.
