The pygmy marmoset is the smallest monkey species in the world. Native to the rainforests of Bolivia, Peru, and Ecuador, they are small enough that an adult can fit in the palm of your hand. The Rare Species Conservatory Foundation in Florida took in a baby pygmy marmoset a few years ago who was rejected by her mother because she is deaf. She wouldn't have much of a chance on her own even as an adult, but has found a permanent home and safety. Ninita gives us a glimpse into the tiny adorable life of a pygmy marmoset. How small are they, really? Check out this clip from the Apple TV+ series Tiny World.
