Pale-lined Tropical Rock Crab

Grapsus albolineatus

This species is a conspicuous rocky shore creature being green, maroon and yellowish-cream colour; with claws having white fingers and purple palms, and splotches of purple on its legs. It may reach 50-60 mm across. They live on, and under, rocks in the upper tidal zone of the sea shore, feeding on algae at low tide. They are very fast and difficult to catch, and can lock themselves into crevices with their strong spiky legs.

Found across northern Australia, with an extended range from East Africa to Japan and Hawaii.
