The Common marmosets are unique primates with a rather unusual appearance and a number of special adaptations. The New World monkeys exhibit a gray overall coloration. Their gray considerably long tails are covered with white and gray stripes. As they age, the animals grow white colored tufts that begin from both sides of their face. The claw-like nails on their feet (known as tegulae) make these primates excellent clingers and leapers. The large intestine allows them to consume large amounts of food. Additionally, these animals have specialized incisors. [SOURCE: ANIMALIA]
