Like their ancestors, they live in big, organized troops. They are curious towards humans, but retaliate accordingly if attacked. They have a sense of altruism and team-spirit, as if one is injured, it will call for help and the rest of the troop will come to it's defense.
They resemble olive baboons, but are a similar size to the larger chacma baboon and share the latter's long legs. They have evolved shaggy, dog-like hair in response to living in the redwood forests, and, like their ancestors, live in large troops.
Their presence in a Canadian redwood forests suggests that they may be descended from feral baboons who escaped laboratories, zoos, circuses, pet-owners, and private breeders.
