The golden lion tamarin is a small primate native to the Atlantic coastal forests of Brazil. It is easily recognized by its striking golden-orange fur and mane-like appearance, resembling a lion. These monkeys typically weigh around 1 to 2 pounds and have a body length of about 18 inches, excluding their long tails. Golden lion tamarins are social animals that live in family groups, often consisting of 4 to 8 individuals. They primarily feed on fruits, insects, and small vertebrates. Due to habitat loss and fragmentation, they are considered an endangered species, prompting conservation efforts to protect their natural environment.
