Slow Loris
Wait! How could the world’s cutest animal possibly the #1 entry on this list? Seriously, look at that face, they can’t actually be dangerous, can they?
These big-eyed fur-balls actually have a poison glad on their elbows, which if ingested will cause severe stomach pain. They typically rub this toxin on their babies to prevent predators for running off with them. Most human deaths from the Slow Loris are a result of anaphylactic shock.
