I think the gorilla would win the weightlifting, and wrestling events in the super-heavyweight divisions. Other primates would probably take the lighter weight divisions.
But how about a python or anaconda in wrestling? And smaller snakes in the lighter weight division. There’s also a lot of running events. Humans may be right up there in the marathon, but what about hurdles, the mile (do they still do that?), and the steeplechase? Different animals may have advantages/disadvantages in those events.
Flying animals clearly have an advantage in jumping events, and even the track events if they aren’t required to touch the track with their feet after the start. I can see the Olympic committee rapidly creating new divisions for those sports.
I’m curious about the high jump if flying animals are removed. Which cat can jump the furthest? I was under the impression a tiger would outjump a leopard. And would kangaroos win the long jump? I imagine they could learn to do the triple jump, but maybe not.
I’m curious about the synchronized sports. Do humans or other species have some kind of physical advantage there? For instance, would the gannets have the highly synchronized behavior of some birds flying in flocks in the synchronized diving event?
How about table tennis? Does any animal that could hold a paddle in it’s hand match the dexterity of humans? I’m suspecting some primates might.
And here’s a big one: Who wins the decathalon? This requires a variety of skills, including pole vaulting. Some non-human primates may be able to pole vault, but how well? And do they stand a chance in the running events?
Blake, polar bears aren’t all that agile when bipedal, so I wonder if a gorilla would be able to outbox a polar bear if it avoids getting knocked out (and maybe killed). If the polar bear touches it’s gloved front paws to the mat, it will be knockdown, although that doesn’t count for much in olympic boxing. So a gorilla or maybe a different kind of bear might have an advantage in agility. But I can’t think of any other animal with even a chance in the super-heavyweight division. Even the humans in that divisions seem kind of slow compared to bears and gorillas. It could get interesting in the lighter weight divisions, though primates would be dominant since not many animals can move well bipedally. Also, would the smaller dolphins have an advantage in water polo? The pool has a limited size and the killer whales might be getting kind of crowded. And eating your opponent is probably a rule violation, although maybe it wasn’t anticipated when they wrote the rules.
