The Marca marmoset^[1] (Mico marcai) is a native endemic to the Amazon in the Aripuanã-Manicoré interfluvium of Brazil.

• Its body is light gray, with orange legs, a black tail, a pink face, and bare ears.
• It is about 23 cm long, not including the tail, and has a tail 15 inches (38 cm) long.
• It weighs about 12 ounces (340 g).

• Marca marmosets are arboreal and diurnal. They prefer to spend most of their time high up in the trees of the upper canopy of the rainforest.
• They live in groups of 4 to 15 individuals. These groups are led by a dominant male and female.
• The dominance hierarchy is determined by age rather than gender, strength, or family relationships.
• Marca marmosets that submit to a dominant individual show this by baring their teeth and laying their ears flat.
• Marca marmosets make regular chirps to stay in contact with their group while feeding.
