Morphology | Morphometrics
Upper lip widest at middle; no papillae in central part of disk (Ref. 26938).
Lives in close association with the sea urchin Echinometra mainly for protection. Feeds primarily on benthic crustaceans like amphipods, but harpacticoid copepods and ostracods are also eaten (Ref. 33548).
