Carapace up to 2.5cm.
Carapace usually reddish/ yellowish and highly nodose (large bumps) and not hairy. Walking legs hairy, claw arms without hairs. Four acute antero-lateral spines or teeth behind orbit. Ridges between carapace sulci little subdivided. Wrist smooth above and with one inner tooth. Spatualate chelicerae (pincers) - pale at tips.
On rocky shores and reefs in crevices and under stones and dead corals. Also between tides and in shallow water at depths from 0-90m (0-300ft).
From a species study in Venezuela: Male and female crabs attained earlist sexual maturity at a size of 7 and 11 mm carapace length )although for 50% of the population was 19 and 16 mm).They can reproduce continuously during the year. Fecundity estimates of ovigerous females ranged from 34 to 4777 eggs (average (mean) 1024 . Fecundity was positively related to carapace length, width and total weight.
