        They’re all trying to move up one shell size, so they position themselves as close to the shell they want as possible. If they weren’t in order, the chance they’d end up shell-less increases dramatically

      Seriously though, if crabs used currency this would never happen. There would be one crab with all the shells and the other crabs would have to bring food offerings or whatever their currency would be in order to get one.

    They also duke it out if two crabs want the same shell. I recall one video where two crabs were goin round the outside when a third one just moves into the shell. Hilarious at scale, but I bet the first two were pissed. Good thing they weren’t pistol shrimp.
