Guianan Squirrel Monkey Facts

Guianan Squirrel Monkeys

  • Saimiri sciureus was once thought to belong to the Collins’ squirrel monkey and the Humboldt’s squirrel monkey. Still, genetic research in 2009 and 2015 showed they were different species.
  • Female squirrel monkeys nurse and groom their young until they are independent. The male species do not participate in the raising of infants.
  • They are incredibly agile and sometimes run through the forest on branches.
  • Guianan squirrel monkeys exhibit female dominance, with females forming the central core of the troop or group.
  • These monkeys are diurnal, and their activities are typically centered around a water source.
