Morphology | Morphometrics
With diffuse dark spots, each with a pale center (bright yellow in life), on a pale tan or greenish-brown background, shading to pale green ventrally (Ref. 26938).
Common near islands and in rocky or coral areas (Ref. 7251). May move beneath the sand (Ref. 9710). Found in seagrass bed sand areas with sand and coral rubble (Ref. 26938). Feeds mainly on crabs (Ref. 32). Forages at night for prey.
