It has a total length of 3.5 cm. Fisheries: It is consumed locally boiled, restrictions due to habitat degradation hamper exploitation in parts of area (Ref. 344). It is infaunal in mud or sandy mud in estuaries, mangrove swamps, and coastal lagoons (Ref. 344). Occurs in intertidal areas and in relatively small numbers in shallow nearshore areas (Ref. 104487).
