Short description

The rostrum is a low blunt angle in the median part of the anterior margin of the carapace, being overreached by the eyes with practically their full length. The eyes are triangular with a blunt top. The antennal angles are low, rounded, without tooth. Antennular peduncle only slightly longer than antennal peduncle. Third maxilliped with ischium and merus strongly widened to form a kind of operculum; the distal three segments much narrower, each about twice as long as wide. Large chela in adult male with a small concavity above the base of the fixed finger. Carpus slightly shorter than palm, about as high as long. Lower margin of merus with a broad forward directed hook-shaped process, which ends in a triangular top. Telson about as long as wide, gradually narrowing posteriorly: the convex lateral margins merge evenly with the posterior margin. Each posterolateral angle bears two very small denticles, no median denticle present. Endopod of uropod broadly oval, slightly longer than telson (Ref. 4).

Biology     Glossary (e.g. epibenthic)

It has a total body length of 2.5 to 6 cm (Ref. 4). It is found in open beaches with a rocky boulder-covered shore (Ref. 262). It constructs rather complicated burrows in the soft sandy substratum (Ref. 4). Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833).
