Description
Narrow vertical bar through eye to bottom of head. Markings highly variable, but tend to be more distinctly linear down the side compared with those of G. anjerensis (Shoulderspot Sandgoby). Shoulder spot is not diagnostic, varying between individuals, and even between sides of a single individual. Found on sand patches near reefs.
