Espinhos dorsais (total) : 4 - 5; Raios dorsais (total) : 15 - 17; Espinhos anais: 0; Raios anais : 14 - 17. Caudal rounded.
Inhabits sand or mud bottom. Retreats into shrimp burrows when threatened and at low tide (Ref. 6885). Commonly in estuaries, lagoons and tidal sloughs. Reported to occur in freshwater. Adults feeds on diatoms, green algae, tintinnids, eggs and young of their hosts (Ref. 6885). Positions large food particles near crabs to be torn to smaller pieces (Ref. 6885). Preyed upon by Sebastes, staghorn sculpin, whitespot greenling, and terns (Ref. 6885). Unlike other gobies, it does not build a nest or care for its young (Ref. 2850).
