{{main|Supralittoral zone}}

The ''supralittoral zone'' (also called the ''splash'', ''spray'' or ''supratidal zone'') is the area above the spring high tide line that is regularly splashed, but not submerged by ocean water. Seawater penetrates these elevated areas only during storms with high tides. Organisms that live here must cope with exposure to fresh water from rain, cold, heat, dryness and [[predation]] by land animals and seabirds. At the top of this area, patches of dark [[lichen]]s can appear as crusts on rocks. Some types of [[Common periwinkle|periwinkles]], [[Neritidae]] and detritus feeding [[Isopod]]a commonly inhabit the lower supralittoral.<ref name="Yip and Madl">Yip and Madl</ref>
