Maximum depth from Ref. 10. Maximum standard length: 24.0 cm (Ref. 356). Found on mud or sandy-mud substrates and prefers turbid waters. Caught mainly by trawl, gill net, fish corral, push net and filter net (Ref. 10). Occurs in bottom mud or sandy-mud substrates in marine and estuarine environments (Ref. 8). Inhabits shallow open sea or in the mouth of a river and bay areas where water is more or less turbid (Ref. 374). Adult species periodically form aggregations or 'schools' offshore (Ref. 100847). 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).
