monkeys and apes make me feel uneasy, think it has to do with their mannerisms being close to that of a humans
was stared out by a baboon at Singapore zoo once, it sat on the otherside of a glass partition and when i looked into it's eyes it looked like a human staring back at me from within the body of an animal, could see the intelligence and i felt the same uncomfortable tension that you'd associate with the presence of another human, almost as if knew what i was thinking, was thinking about reincarnation, really freaked me out!
