Do they just not want somecrab standing on top of them? Is it involuntary?

Its actually not true as far as why they’re doing it. It isnt to make sure the other crab doesn’t get out first, its because crabs are dumb and dont know to work together to get out easier. They just flail their legs and try to climb out, sometimes it pulls another crab down accidently.

They do however very easily climb out of buckets, don’t let the old saying make you think otherwise.

They aren’t trying to pull each other down, they’re just stupid enough to think “Hey! I could grab onto Jeff’s leg and pull myself up!” not realising that Jeff up there isn’t really holding onto anything strongly enough to support both their weight.

They aren’t trying to pull each other down, they are all just trying to climb at the same time, and in doing so, pull each other down. Each individual crab is doing what is best for it to get higher in the short term, but make long term escape impossible.

Humans do the same thing. When there is a fire and a big crowd is trying to exit through a door that opens in, everyone rushes to the door, thinking they are getting closer to escaping, but they actually are only pinning the people in the front against the door, making it impossible for it to be opened.
