How do rocky coast life zones differ from those of the sandy beach?

Rocky coast life zones are characterized by diverse habitats created by tidal pools, crevices, and varying elevations, supporting a wide range of organisms such as sea stars, anemones, and barnacles that thrive in harsher, more dynamic environments. In contrast, sandy beach life zones feature softer substrates that shift with tides and wave action, leading to adaptations in organisms like crabs, clams, and shorebirds that are better suited for burrowing or quick movement. The stability and nutrient availability also differ, with rocky areas often providing more shelter and food sources compared to the more transient and less stable sandy environments.
