Steinitz' Prawngoby

Found singly or in pairs, sharing their burrow with an alpheid shrimp, where they can be found sifting through sand with their mouths looking for food, over sandy bottoms of estuaries, lagoons, and seaward reefs.

Shrimp Gobies live a symbiotic relationship with snapping shrimps.
The Gobies stand guard while the shrimps play "housekeeper" to their burrow, continually digging and cleaning the sand. The Gobies will signal when predators are near.
