Adults live in subtidal areas and are rarely found in intertidal areas. They feed on organisms which inhabit encrusting rock growths, with amphipods and hermit crabs being the dominant food items (Ref. 26966). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
