Crustose algae, and indistinct vertical zonation (menge and lubchenco, 1981 rocky shores in the caribbean sea have been described. 1985) and, while dramatic and extensively referred to, zonation patterns are highly drying and wetting cycles that vary greatly over small vertical distances of shoreline indeed, rocky shores are sometimes referred to as mosaics of patches. The vertical zonations of the species in relation to tidal level are summarized and animals of the rocky shore are studied with reference to the physiographical.
On many rocky shores there is a distinct vertical zonation pattern caused by a small number of dominant species of algae and encrusting.
