Pygmy Marmoset

Cebuella pygmaea

The pygmy marmoset (Cebuella pygmaea) is a very small New World monkey from western Amazonian forests, especially river-edge woodland and seasonally flooded forest. Adults are short-bodied with a long banded tail, grizzled brown-gold fur, and a mane-like face that makes the head look larger than it is. Like other callitrichids, they have claw-like nails on most digits and specialized lower incisors used to gouge bark and vines for gum. Taxonomy has shifted in recent years, with some authorities recognizing more than one pygmy marmoset species or regional form.

Because they are tiny, social, scent-marking primates with complex diets, pygmy marmosets are poorly suited to private pet keeping and are regulated in many places. Zoos and specialist sanctuaries usually house them as bonded pairs or family groups in warm, humid enclosures with dense branches, nest boxes, visual cover, and gum-feeding devices. Diet planning combines exudates or gum substitutes with insects, fruit, and a formulated primate ration; over-sweet feeding can cause health problems. Infant care is shared by the father and older siblings, so stable group composition matters as much as enclosure design.
