Slow Loris
The slow loris is a species of nocturnal primates that eat mostly fruits and insects. As their name suggests, they do not move very quickly, which makes them susceptible to predators. But any enemy that dares is in for a not-so-tasty surprise. It is one of the few venomous mammals on earth and the only venomous primate.
The slow loris has poisonous glands on its arms that it rubs on its fur as a way to defend itself with a special coating. When it is attacked, the creature will raise its arms over its head and assume a posture. The secretion mixes with the saliva to pack a bite so powerful it could kill a human being.
