Hermit Crab Swarm

A churning carpet of hermit crabs queuing to upgrade their shells becomes a snapping, coordinated mass the instant it's disturbed.

commonAmphibiousAnimalSwarm

When hermit crabs find a shell that's too large, they lie in wait for others to arrive and move into the shell, abandoning a possible replacement. This can form a large chain of queuing crabs waiting to upgrade their shells—and a churning, snapping carpet of them when disturbed.
