Soldier Crab

Mictyris platycheles H. Milne Edwards, 1852

Commonly seen at low tide moving in large groups across the sand as they feed and quickly burrowing into the sand when disturbed. It is this large colony or group movement that gives them their common name.

These crabs roll up balls of sand to feed on as they move along leaving the balls behind as they go. These balls are visible along the beaches once the crabs burrowed away to await the next high tide when they repeat this process over again.
