If you were to list the most fearsome body parts of a wild animal, teeth and claws would probably be at the top of the list. I doubt elbows would even crack the top 10, but that’s exactly where the slow loris gets its venom. When threatened, the loris licks a gland on its elbow, and the saliva activates the venom. The loris then bites, delivering the venom and deterring the predator. The loris is unique in how it gets its venom and also in that it is the only venomous primate.
