Soldier crab

Crustacea | Ocypodidae
Mictyris brevidactylus


The soldier crab is a cute, round crab. The crab is light blue on its cephalothorax and, in contrast, bright red on the root of its pereopods. Despite its cute appearance, it has a very masculine common name: the “solider crab”. Unlike other crab species, which move sideways, the solider crab moves straight forward. When faced with danger, the crabs burrow into the sand in a corkscrew motion and wait for a safe moment to come out.


The soldier crab moves in groups on sandy mudflats at Gaomei Wetlands.
