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 long, tufted mane, resembling a lion's mane. These monkeys typically weigh around 1 to 1.5 kilograms and have a body length of about 24 to 26 centimeters, 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, their population has declined, making them a focus of conservation efforts, including those by organizations like the World Wildlife Fund.
