Black Tufted-ear Marmoset (Callithrix penicillata)



MORPHOLOGY:
The black tufted-ear marmoset has nonopposable thumbs and nails of the digits which are claw-like.

RANGE:
The black tufted-ear marmoset is endemic to the forests and savannas of Brazil, which tend to be seasonal habitats (Rylands et al., 1993).

ECOLOGY:
Gums make up >70 % of the plant part of the diet of the black tufted-ear marmoset (Fonseca and Lacher, 1984). Being highly gummivorous may explain why the black tufted-ear marmoset has a small home range (Rylands and de Faria, 1993).

LOCOMOTION:
This species moves through the forest quadrupedally, but is capable of leaping (Fleagle, 1988).

SOCIAL BEHAVIOR:
This species is reproductively monogamous.

VOCAL COMMUNICATION:

OLFACTORY COMMUNICATION:
The black tufted-ear marmoset scent-marks at tree sap holes which may communicate time between usage for a specific group, preventing two different groups meeting at the same holes in a tree at the same time (Lacher et al., 1981).

suprapubic marking: this is when an individual presses the suprapubic pad against a substrate and deposits secretions by pulling itself along or by pushing itself with its feet (Epple et al., 1993). This behavior pattern is frequent in the black tufted-ear marmoset and can occur more frequently by an individual where the home ranges of two groups overlap, thus suggesting a use for demarcation of territory (Rylands, 1990).

VISUAL COMMUNICATION:

TACTILE COMMUNICATION:

REPRODUCTION:
This species gives birth to twins (Fleagle, 1988).
