Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 40 - 44; Dorsale zachte stralen (totaal): 0; Anale stekels 1; Anale zachte stralen: 38 - 42. Caudal rounded, somewhat elevated dorsally; pectorals small and rounded (Ref. 6885). Color variable- from green through brown to red; dark dots spaced in a broken line along midside of body, sometimes also light spots; narrow dark line down and back from eye to operculum, sometimes through eye; some fresh specimens with a silvery line margined with orange and black from middle of maxillary through lower part of eye to nape and opercle (Ref. 6885).
Facultative air-breathing in the genus (Ref. 126274); Found in intertidal areas, especially in tide pools (Ref. 2850). May remain out of the water under rocks or seaweeds (Ref. 31184). Feeds on small crustaceans and mollusks (Ref. 6885). Pairs are found coiled around egg masses (Ref. 4925). Breathes air when out of water (Ref. 31184).
