Years ago, on my first trip to Africa, I was spending my first night out in the bush, when I awoke with a start. I became aware that there was an animal outside my tent, shuffling around. Fascination turned to fear, seconds later, when whatever it was let out an ear-piercing shriek and started smacking into the side of my tent. I was pretty sure for a few seconds there that my first night on safari would also be my last.
The late night visitor, surprisingly, ended up being a pint-sized bat-eared fox. Talking around the breakfast table the next morning, my companions - all who were safe and snug in their tents during this - had expressed their fears that there was a lion or a hyena in the camp, which could have done much more damage. I guess I agreed. I hadn't quite realized it at the time, but what had really scared me more than anything that night, what I really, really was afraid I'd see when the side of the tent tore open, was a baboon. And that I was glad that I wasn't in a part of that country that had chimpanzees.
A lot of people are famously afraid of clowns. The same can be said about skeletons, and zombie horror is a popular genre. I think I heard it explained to me somewhere that we're afraid of these things because they are sort-of, but not quite, human in our eyes. They are close enough to be like us, but our brain perceives something different and, therefore wrong and worrying about them. With that in mind, I'm surprised that the fear of apes and monkeys, pithecophobia, isn't more of a thing.
There's something that I find very unnerving about a lot of non-human primates, and the more closely related they are to humans, they more off-putting I can find them. They're the animals that I've probably enjoyed working with the least; the one day that I spent filling in for the chimp keepers, in the cavernous depths of their holding building, echoing with shrieks and the rattling of doors, was one of the creepiest experiences of my life. Years later, when I watched Silence of the Lambs for the first time, that scene in which Clarice Starling first walks down the hallway of the insane asylum, past the various psychopaths as she made her way to Hannibal Lecter, reminded me of that day.
I find zookeepers very divided on the subject of chimps, which, being the most human-like of the primates, are also the most violent and mercurial. Some of them absolutely adore them, finding their closeness to us fascinating and incredibly, and delighting in their intelligence and behavioral complexity, their dynamic social lives. Others are horrified and disgusted by them - their grossness, their loudness, their brutality, to each other and to other animals. One registrar I spoke with likened reading the daily report of the chimp keepers to a catalog of injuries that they inflicted upon each other, seemingly on a whim. A former keeper who visited me at one zoo where I worked literally put her hands over her eyes as she walked past our chimps, asking me to guide her by and let her know when she had passed them. I know of no other zoo animal that is so polarizing among keepers as to how they feel about it.
When most animals defecate on you, or threaten you, or display a sexual fixation on you, it can feel unpleasant enough, but you brush it off, usually. When it's an ape, or a large monkey, however... well, it feels creepier, and a lot more personal. It becomes harder to think of it as animal expressing that hostility and/or lust (they two have a weird habit of going together with primates), and more like a strange, wild person.
I'll throw myself on the back of an alligator, or wrangle an anaconda. I'll go in with wolves and cheetahs. I'll walk a thin catwalk above a shark tank. But ask me to work chimps again? Sorry, I think I have to wash my hair that day... and not just because the damn monkeys pooped in it again.
