Thumb Sucking Acrobat

A baby orangutan takes thumb sucking to a new level thanks to prehensile feet. Much like human children, baby orangutans remain dependent on their moms for a long time, sometimes being carried most of the time until they re 5 years old. Young orangutans normally don t leave mom s side until they re 10 or so, and even when they do strike out on their own, they often return to visit for the next few years.
