Spider Monkey features long limbs and a prehensile tail that they can use to pick up items. The arms are so long that they drag on the ground when they walk. You often won’t see them as they remain in the high canopy of the rainforest. Thy consumes leaves, insects, and seasonal fruits. They are very social and their family groups can have up to 35 members in them. Should there become a risk to survival such as a lack of food or shelter then they may break up into smaller groups. Thy weighs from 21 to 24 pounds.
