A flat green-brown crab with hairy legs, wedged into crevices and out grazing algae after dark.
This entry is short because the sources are effectively empty. No maximum size, no depth range, no colour description and no confusion species could be found for it in any database or guide consulted.
What can be said at genus level, and is labelled as such: the clinging crabs are squat, broad-carapaced crabs that wedge into crevices and graze algae at night.
The genus placement is also unsettled, with the species carried under both Mithraculus and Mithrax. Note as well that “hairy clinging crab” is the standard name for a different Caribbean species, so the name on this page collides with one already in use.
This entry needs a printed Galapagos crustacean guide before it can say more.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
