Facts about Silvery Marmosets
- 09
Each silvery marmoset group maintains home ranges of approximately 0.5 to 1.5 square kilometers within the Amazon Basin, which they defend against rival troops through coordinated territorial displays.
- 08
Long-term pair bonds in silvery marmosets often last the entire reproductive lifespan, with both parents actively involved in infant care and carrying duties.
- 07
Nocturnal foraging behavior allows silvery marmosets to hunt insects and small arthropods during nighttime hours when diurnal predators are less active in the Brazilian rainforest canopy.
- 06
In captivity, silvery marmosets can live 10 to 12 years, significantly longer than their typical 8-year lifespan in the wild.
- 05
Silvery marmosets live in social groups of 4 to 15 individuals with a strict hierarchical structure where only the dominant female typically reproduces.
- 04
Found exclusively in the Amazon Basin of Brazil, silvery marmosets communicate through at least 13 distinct vocalizations including high-pitched trills and alarm calls.
- 03
Their specialized teeth include sharp canines and elongated lower incisors that silvery marmosets use to gouge tree bark and access gum, a dietary staple comprising up to 70 percent of their food intake.

Silvery marmosets typically give birth to twins after a gestation period of approximately 140 to 150 days, making them among the most frequently twinning primates.
- 01
Weighing only 350 to 500 grams, silvery marmosets are among the smallest primates native to South American rainforests.
