Morphology | Morphometrics
Vertebrae: 114 - 118. Drab yellow or brown in color, overlain with a web-like network of dark thin lines (Ref. 3257).
Abundant on rubble areas of intertidal reef flats. Feeds on small crustaceans and probably on small fishes as well. Also found in shallow reefs including tide pools (Ref 90102).
