Taxonomy, Evolution, and Description

Description 

Physical description of the animal: The Pygmy Marmoset has speckled, tawny fur and a hood of hair on its head. Like other marmosets, the Pygmy Marmoset has claw-like nails that help them to climb. The tail is 17–23 cm long, which is longer than the body, and marked with black rings.

Point key characteristics of species: They have longer arms than legs. Pointed Claws. Tails are longer than their bodies. Tiny ears. 

Size: 117 to 152 mm (4.6 to 6.0 in)

Weight: 119 g (4.20 oz) 

Life Span: 15-20 years. They are known to have a shorter life in the wild mainly because they fall out of trees.

Differences between Males and Females: A noticeable physical difference between genders is weight, with males weighing in at 3.77-4.41 ounces (107-125 g), while females weigh a bit more at 4.44-4.97 (126-141 g). Male and female pygmy marmosets show differences in foraging and feeding behavior. Males have less time to search out food sources and forage due to the constraints of their infant-caring responsibilities and predator vigilance. Without an infant to carry, female pygmy marmosets have greater freedom to forage, giving them an apparent feeding priority.
