Pygmy Marmoset

Pygmy marmosets are the world’s smallest true monkeys. (The smallest primate is the pygmy mouse lemur.) Pygmy marmosets are not sexually dimorphic. Adults are about five inches (13 cm) long with an eight-inch (20 cm) tail and weigh four to seven ounces (113 to 199 g). The fur is buff and gray with yellow and green striations, which give it a grizzled effect on the head and back and a vague banded effect on the tail. They have long hair on their heads and chests giving the appearance of a mane. Their coloration provides great camouflage for their lives in the trees.
