The Cottontop Tamarin (Saguinus oedipus), also known as the Pinché Tamarin, is a small New World monkey weighing less than 1lb (0.5 kg). It is found in tropical forest edges and secondary forests where it is arboreal and diurnal. This tamarin species has a long sagittal crest, white hairs from forehead to nape flowing over the shoulders (“Cottontop”). The back is brown, and the underparts, arms and legs are whitish-yellow. The rump and inner thighs are reddish-orange. It is considered one of the bare-faced tamarins because of the lack of facial hair. Its lower canine teeth are longer than its incisors, so it seems as if it has small tusks. It is about the size of a squirrel and weighs 10-18 ounces. The males are only slightly larger than females. A medium Cottontop Tamarin weighs 432 g. Tamarins are among the smallest of the primates. Head body length of this species is 17 cm and tail length is 25 cm. Forelimbs are shorter than the hind limbs. The thumb is not opposable and the tail is not prehensile. All the finger and toe nails are like claws except for the big toe which has a flat nail.
