Term Supralittoral zone
Definition

A geographic area along the coast that is underwater during high tide and exposed to air during low tide.  In this zone, vegetation is dominated by algae, which can form a wide belt measuring up to two meters.

In the Dominican Republic, the most common species of flora in the intertidal zone are Chaetomorpha media, Sargassum rigidulum, Turbinario turbinota, Padina sp., Enteromopha flexuosa, Bryopsis pennata, Laurencia obtusa, and Valonia ventricosa.  Studies carried out on the protected rocky littoral zone of the Andrés Bay in the province of Santo Domingo found 47 species of algae, among which Ulva, Enteromorpha, Padina, Dyctiota, and Dictyopteris are the most common.  The predominant fauna in this zone includes molluscs, such as sea roaches, clams, oysters and snails; marine invertebrates such as sea worms; and crustaceans, including crabs
