The subtidal area is the last zone we will discuss. This area is submerged most of the time, exposed briefly during extreme low tides around full and new moon events. This zone provides habitat to a large diversity of plants and animals in contrast to the other zones. It is dominated by red algae and the most common animals found here are the grazers such as periwinkles and sea urchins.
The zone that begins where the intertidal zone ends is called the subtidal zone. This zone is constantly submerged underwater and experiences minimal exposure to air during low tides. It is characterized by deeper waters and different marine life compared to the intertidal zone.
- the intertidal zone - the sublittoral zone - the bathyal zone - the abyssal zone and - the hadal zone
Below the low tide line, you would expect to find organisms adapted to subtidal conditions such as kelp, sea stars, crabs, mussel beds, and various types of seaweed. These organisms are capable of withstanding the force of waves and the depth of the water at that level.
The Central Time Zone is east of the Mountain Time Zone.
The Pacific Time Zone is west of the Mountain Time Zone.
it is always covered in water

The type of animals that are typically absent in a soft bottom subtidal community are sessile. A sessile animal is not able to move and is permanently attached to something solid.
Starfish are found in all temperate or tropical oceans. They are hugely adaptable and can live happily on sandy, coral, muddy or rocky seabeds. They are most abundant in the Atlantic ocean.
The intertidal ecosystem has the most life in it, it is between high tide and low tide and is always changing. Organisms that live in this area must be able to live with water and no water, also have protection from sea gulls and other sea birds that prey there. Some examples of animals that live there are ghost crab, coquinas, skates, and sand dollars. there are different zones in that too, like that beach zone and subtidal zone for example.
The majority of mollusca species live in marine environments, and many of them are found intertidally, in the shallow subtidal and on the continental shelf.
Benthic, anywhere from the sub-littoral to the subtidal to the abyssal. Depends on the species. They generally prefer a rocky bottom.

Gary Mc Meekan has written: 'The development of a sampling apparatus for the in situ collection of interstitial water from subtidal and intertidalsediments for radiochemical analysis'
Organisms in the intertidal zone experience greater extremes of temperature and wave action than organisms in the near shore zone.
Finger Sponges are found southwards from Western Australia to the central New South Wales coast. Finger Sponges live in coastal waters and on subtidal rocky reefs.
