BiologyOccurs in intertidal zones in large rock pools or coastal bays (Ref. 48636). Found near-shore (Ref. 9962); common in tide pools (Ref. 559). Oviparous (Ref. 205). Eggs are demersal and adhesive (Ref. 205). Feeds on algae scraped from rubble or rock surfaces. Sometimes numerous individuals can be seen clinging to rocks out of the water when the level drops on the low of the swell. When disturbed in rock pools during low tide, they may jump out of the water to get to other rock pools or safer deeper water nearby (Ref. 48636).
