Macaque Monkey Adopted Kitten, Bali, Indonesia

In some species skin folds join the second through fifth toes, almost reaching the first metatarsal joint.
Macaques also have a very intricate social structure and hierarchy. If a macaque that is lower level in the social chain has eaten berries and there are none left for a higher level macaque, then the one higher in status can, within this social organization, remove the berries from the other monkey's mouth.
