Estuarine, intertidal, artificial, lagoon, eulittoral

Artificial surfaces on the shoreline are common near most areas of human activity, as docks, breakwaters, seawalls, and other constructed habitats, including 'lagoons' that may be man-made or modified. Biological communities on these surfaces are likely to be a subset of those on nearby rocky shores, although the presence of freshwater, creosote or other anti-fouling chemicals may greatly restrict abundance and diversity of species that can survive there.
