The Golden Lion Tamarin is a small monkey, usually 25 cm tall (not counting their tail) with puffy golden fur, a brown, furless face, a long tail which is sometimes mottled black, brown or gold and opposable thumbs. It is hard to tell the difference between males and females.
The Golden Lion Tamarin is a small, endangered monkey who lives in rainforests. It is a species of Tamarin, a group of squirrel-sized New Age Monkeys and is a mammal. Their scientific name is Leontopithecus rosalia .
The Golden Lion Tamarin can be found in coastal tropical rainforests in Brazil, preferring lowland areas. It is commonly found in hollow trees 3-10 metres above the ground, usually with a hole lined with body fur as their home. This is too small for nocturnal predators to get in.
The Golden Tamarin usually mates in April and May and give birth in September and March. They usually have twins and have a gestation period of 125 to 132 days. Adult Golden Lion Tamarins can only mate with one of the opposite gender and both the male and female care for their young. The babies are weaned at 5 to 6 weeks, usually by the mother. Males reach sexual maturity at 18 months and females at 24. Upon reaching this stage they are driven out of their family territory to go find a mate. It has been known that mature Golden Lion Tamarins can become aggressive with their children.
During the day Golden Lion Tamarins search for food. They mark territory boundaries with scent glands found on their chest. In the evening they will go back to their tree holes. They are very active and vocal but usually their calls are soft and quiet. This is believed to keep them safe from preying hawks and eagles.
