Although venom is common in the animal kingdom, it is not so common in mammals specifically. In fact, there is only one known species of primate that produces toxic venom, called the slow loris.
This endangered nocturnal primate resides in southeast Asia, and eats anything from tree-gum to small reptiles and birds. It isn’t especially large, but the slow loris’s venom makes it incredibly deadly.
Watch the video to learn more about the slow loris, and to see some rare footage of it in the wild.
