尾鰭圓的。
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).
棲息於沙或泥底部。 撤退進入蝦洞穴裡面當危險時而在低潮.(參考文獻 6885) 通常在河口, 潟湖與潮汐的泥坑中。 報告出現在淡水。 成魚吃矽藻，綠藻， tintinnids ，卵與其寄主的幼生。 (參考文獻 6885) 放置在螃蟹附近的大的食物粒子被撕開到較小的塊。 (參考文獻 6885) 被 Sebastes ， staghorn sculpin ， whitespot greenling 與燕鷗捕食了。 (參考文獻 6885) 不像其他的鰕虎魚，它不會為它的幼魚建立一個巢或照料。 (參考文獻 2850)
