The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life , such as sea stars , sea urchins , and many species of coral with regional differences ...
Many mobile organisms, such as snails and crabs, avoid temperature fluctuations by crawling around and searching for food at high tide and hiding in cool, moist refuges (crevices or burrows) at low tide. [10] Besides simply living at lower tide heights, non-motile organisms may be more dependent on coping mechanisms.
The high tide zone is flooded during each high tide, which occurs once or twice daily. Organisms must survive wave action , currents , and long exposure to the sun and open air. [ 4 ] This zone is predominantly inhabited by seaweed and invertebrates , such as sea anemones , sea star , chitons , crabs , green algae , and mussels .
These divisions are the Spray zone, High intertidal zone, Middle Intertidal zone, and Low intertidal zone. The Spray zone is a damp area that is usually only reached by the ocean and submerged only under high tides or storms. The high intertidal zone is submerged at high tide but remains dry for long periods between high tides. [15]

The Spray zone is a damp area that is usually only reached by the ocean and submerged only under high tides or storms.

The wrack zone is most commonly associated with a sandy beach habitat but can also be present in rocky shores, mangroves, salt marshes, and other coastal systems. [1] Debris is carried up the intertidal zone as the tide comes in, and is deposited on the sand when the tide goes out.
The intertidal zone is the area between high and low tides. Other near-shore (neritic) zones can include mudflats, seagrass meadows, mangroves, rocky intertidal systems, salt marshes, coral reefs, lagoons. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.
The area around the high-tide mark is known as the intertidal fringe. Between the high and low-tide marks is the intertidal or littoral zone. Below the low-tide mark is the sublittoral or subtidal zone. The presence and abundance of different animals and algae vary in different zones along the rocky shore due to differing adaptations to the ...
