Patella vulgata is found wherever there is substratum firm enough for its attachment on rocks, stones and in rock pools, from the high shore to the sublittoral fringe. It is abundant on all rocky shores of all degrees of wave exposure although the highest densities of Patella vulgata coincide with wave exposed conditions. The species is usually not abundant on shores with a dense growth of seaweed. Patella vulgata extends into estuaries, surviving salinities down to about 20 psu. The conical shell of Patella vulgata is up to 6 cm long with radiating ridges and the apex central or slightly anterior. Individuals from the high shore generally have a taller shell and smaller shell length when compared to juveniles and low shore animals.
