Detailed explanation-1: -The intertidal zone is the area of the shore that lies between the highest normal high tide and the lowest normal low tide. It is also called littoral zone. It can be further subdivided into: high tide zone or high littoral zone.

Detailed explanation-2: -The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.

Detailed explanation-3: -The high intertidal zone is flooded during the peaks of the once or twice daily high tides, and out of the water for long stretches of time in between. Here plants and animals are used to living above the water surface. The middle intertidal zone is generally submerged, except for a period during the turn of low tide.

Detailed explanation-4: -The intertidal zone–the area between high and low tides–is a harsh and unforgiving habitat, subject to the rigors of both the sea and the land. It has four distinct physical subdivisions based on the amount of exposure each gets–the spray zone, and the high, middle, and lower intertidal zones.

Detailed explanation-5: -The rocky intertidal zone is characterized by environmental extremes (temperature, salinity, desiccation, nutrient supply), yet there are also strong biotic interactions determining community structure. Macroalgae play important roles as the dominant in situ producers, forming the base of local food webs.
