Tide pool
A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. These pools typically range from a few inches to a few feet deep and a few feet across. Many of these pools exist as separate bodies of water only at low tide, as seawater gets trapped when the tide recedes. Tides are caused by the gravitational pull of the sun and moon. A tidal cycle is usually about 25 hours and consists of two high tides and two low tides.
Tide pool habitats are home to especially adaptable animals, like snails, barnacles, mussels, anemones, urchins, sea stars, crustaceans, and small fish, as well as seaweed. Inhabitants must be able to cope with constantly changing water levels, water temperatures, salinity, and oxygen content. At low tide, there is the risk of predators like seabirds. These pools have engaged the attention of naturalists and marine biologists, as well as philosophical essayists: John Steinbeck wrote in The Log from the Sea of Cortez, "It is advisable to look from the tide pool to the stars and then back to the tide pool."
Tidal pools are theorized to be one possible environment where life on Earth originated, with the chemical reactions needed for life's beginnings potentially occurring in these shallow, dynamic environments. Additionally, the conditions within tidal pools, such as the presence of fluctuating water levels and unique chemical concentrations, may have also driven the evolution of land-walking vertebrates from ancient fish approximately 400 million years ago.
Some examples have been artificially augmented to enable safer swimming (for example without waves or without sharks) in seawater at certain states of the tide.
The rocky shoreline exhibits distinct zones with unique characteristics. These zones are created by the tidal movements of water along the rocky shores from high to low-tide. They are:
The presence and abundance of flora and fauna vary between zones along the rocky shore. This is due to niche adaptations in response to the varying tides and solar exposure.
Tide pools exist in the intertidal zone (the area within the tidal range), which is submerged by the sea at high tides and during storms. At other times, the rocks may undergo other extreme conditions, such as baking in the sun or being exposed to cold winds. Few organisms can survive such harsh conditions.
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. This zone is predominantly inhabited by seaweed and invertebrates, such as sea anemones, sea star, chitons, crabs, green algae, and mussels. Marine algae provide shelter for nudibranchs and hermit crabs. The same waves and currents that make life in the high tide zone difficult bring food to filter feeders and other intertidal organisms.
