The Cottontop Tamarin (Saguinus oedipus), also known as the Pinche Tamarin, is a small New World monkey weighing less than 1lb (0.5 kg).
It is an endangered species found in tropical forest edges and secondary forests where it is arboreal and diurnal.
This tamarin species has a long crest, white hairs from forehead to nape flowing over the shoulders.
The back is brown, and the underparts, arms and legs are whitish-yellow.
Rump and inner thighs are reddish-orange.
They are most active from sunrise to sunset, they spend a large portion of their activity time foraging for animal prey, searching through leaves and along branches, and peering and reaching into holes and crevices in branches and tree trunks.
When alarmed or excited, Cottontop Tamarins raise the hair on the crown of their head and stand up tall to make themselves look bigger.
