Detailed explanation-1: -A sandy shore is characterized by a sandy profile from the point where wave action reaches the sediment bed, through a wave-dominated subaqueous zone and a wind and wave dominated beach, up to the dune belt where aeolian processes dominate.

Detailed explanation-2: -Some adaptations are an increased ventilation rate, an increased ventilation efficiency, reduced metabolic rate or other ways of energy economy. Many sheltered-shore animals are facultative anaerobes as an adaptation to ebb tides. Other animals in oxygenated surf-swept beaches are essentially aerobic.

Detailed explanation-3: -Among the many permanent residents in the infauna are rotifers, some copepods, ostracods, flatworms (turbellarians), and nematodes. The macrofauna of exposed beaches consists of polychaetes (bristleworms), crustaceans (isopods, amphipods, crabs, and ghost shrimp), and mollusks.

Detailed explanation-4: -Sandy shores, also called beaches, are coastal shorelines where sand accumulates. Their slope, and dunes are heavily influenced by the tides and wind. They are often found on the Eastern Seaboard on the United States, as well as many areas in the Tropical Pacific. Some salt marshes can be found around these shores.
