Ashy-gray Titi (Callicebus cinerascens)
MORPHOLOGY:
The dental formula is 2:1:3:3 on both the upper and lower jaws (Ankel-Simons, 2000). The tail of the ashy-gray titi is not prehensile. The forehead, crown, sides of the body, chest, belly, limbs, and tail are grayish to blackish agouti (Hershkovitz, 1990). The middorsum is tawny agouti in coloration (Hershkovitz, 1990).
RANGE:
The ashy-gray titi is found in the country of Brazil (Hershkovitz, 1990). This species is found in southeastern Amazonas, Rondonia, and Mato Grosso in the upper Madeira basin (Hershkovitz, 1990). This species lives in forests in riverine areas (Rowe, 1996). The ashy-gray titi is a relict species of the stock that gave rise to all of the species of the moloch group (Hershkovitz, 1988).
ECOLOGY:
The ashy-gray titi is a diurnal and an arboreal species.
LOCOMOTION:
The ashy-gray titi moves through the understory of the forest quadrupedally as well as by leaping (Fleagle, 1988).
SOCIAL BEHAVIOR:

OLFACTORY COMMUNICATION:
VISUAL COMMUNICATION:
TACTILE COMMUNICATION:
