Broad-banded Shrimpgoby

Found singly or in pairs, sharing their burrow with alpheid shrimps, over sandy bottoms of lagoons and reef slopes, of outer and seaward reefs.
They feed on small crustaceans and fish passing by their burrows.

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.
