Spine dorsali (totale) : 6; Raggi dorsali molli (totale) : 11 - 12; Spine anali: 0; Raggi anali molli: 12.
Body shape (shape guide): elongated.
Lives in burrows excavated in clean sand, often in association with the sandprawn Callianassa kraussi (Ref. 52193). Restricted to sandy, quiet water areas and is unable to form burrows where the substrate is disturbed by water movements, is muddy or consists of sand with a particle diameter > 0.5 mm (Ref. 28077). Food consists of slow moving benthic organisms like chironomid larvae, gastropods, bivalves and amphipods (Ref. 28077). Breeds throughout summer, males are territorial (Ref. 52193). On exposed shores, they occur deeper than 3.5 m (Ref. 28077, 2798). Occasionally intertidal.
