When threatened, callimicos will bolt downwards in the trees to hide among the lowest branches, vines, roots and shrubs.
Status in the Wild
Callimicos have thick, soft, black to brownish-black fur with a short mane atop their head as well as jaw whiskers on either side of their face. They have long, slender fingers with claw-like nails that they use to dig out insects from narrow crevices in rocks and trees. Callimicos have 3 molar teeth, unlike tamarins and marmosets, who only have 2.
The callimico's status is vulnerable and their greatest threat comes from logging and the expansion of human developments in their territories.
