Globular; adults have sky blue body. To more than 25 mm across.


Burrows corkscrew-like into intertidal muddy sandflats. Thousands of crabs emerge on falling tide, to form characteristic 'armies'.

Indigenous, eastern Australia.

Another smaller, less colourful species, Mictyris livingstonei, lives under the shade of mangroves, but does not emerge to march.
