The average body mass for an adult golden lion tamarin is about 600 grams (Ford and Davis, 1992). The name lion comes from the golden mane surrounding the head (Ford and Davis, 1992). This species has long digits used in the forging small insects and vertebrates (Garber, 1992). This species has nonopposable thumbs and the nails of the digits are claw-like.
The golden lion tamarin is found in the country of Brazil, and is found on the Atlantic coast in the East. This species is found in the coastal lowlands, below 300 meters (Rylands, 1993).
The golden lion tamarin is frugivorous, feeding on soft, sweet fruits, but will also eat flowers, nectar, insects, and small invertebrates (Kleiman et al., 1988). The golden lion tamarin has also been known to gnaw into bark for gum (exudates) like Callithrix species (Peres, 1989). This species is arboreal and diurnal. The golden lion tamarin has an average group size of around 5.8 individuals (Dietz and Kleiman, 1986). This species sleeps in tree holes during the night, and the dependence on tree holes might be an ecological constraint for the golden lion tamarin (Rylands, 1993). Both males and females disperse in this species (Baker, 1987).
The golden lion tamarin moves quadrupedally through the main canopy of the forest (Fleagle, 1988). When climbing down tree trunks, the golden lion tamarin will either be in head down or tail down posture (Kleiman et al., 1988).
Primarily the golden lion tamarin has a monogamous mating system, but polygyny and polyandry has also been seen in the wild (Rylands, 1993). Polgyny may occur in populations where there is overcrowding and a low chance of dispersal (Dietz and Baker, 1991). Polyandry may come about when there are more than one adult male in a group and a need to defend the reproductive female, or the female may want to increase the number of male helpers by confusing paternity (Rylands, 1989). In this species social suppression of ovulation does not occur, which is unusual amongst the callitrichids (Kuderling et al., 1992). Food sharing is more important in this genera than other callitrichids, and is important in maintaining the social structure (Brown and Mack, 1978).
long call: The function of this call of the golden lion tamarin is to maintain pair bonds and to signify a group's presence in their territory (Kinzey, 1997).
