Minimum depth based on ecology. Abundant in coastal waters (Ref. 73156). Occurs from the low intertidal to a depth of 119 m (Ref. 122977). Also found in a coastal lagoon (Ref. 122976). Firmly attached by a strong byssus to rocks, shells and rhizomes of the seagrass Posidonia oceanica (Ref. 122975). Occurs either as solitary individuals. Attaches to rocks covered with photophilic algae and nestles in rock crevices and holes in loose stones; also occurs on various kinds of semi-mobile gravels (Ref. 122977). Associated with coralligenous assemblages, i.e. temperate reefs of the Mediterranean (Ref. 122117).
