The opossums who visit my front porch regularly have fully opposable thumbs on their hands and feet. Koalas, Chimps, Orangutans Gorillas, Gibbons (on their feet as well) Lemurs (most of them), and Tarsiers also have opposable thumbs. I'm probably forgetting others. Pandas don't really have a thumb, it's more of a partially opposable nub.
