intertidal zones. There are three generally recognized tidal zones on every coastline in the world. • The spray or splash zone (supralittoral), • The mid-tide zone (midlittoral) • And the low-tide zone (infralittoral). The spray zone is not submerged by normal tides (it is by storm swells) and generally is relatively bare of life. Ocean Habitats – The Intertidal Zone Teachers: This lesson contains four activities with discussion questions related to the AFG video clips about ocean habitats. These parts may be used individually or together, depending on the needs of your class and your time constraints.

TO illustrate the geodynamic forces that create the intertidal zone environment. TO introduce the biology and ecology Of the inter- tidal zone.
Thirdly, because of the intertidal zone's high exposure to the sun the temperature range can be extreme from very hot to near freezing in frigid climates (with cold seas). Lastly, the salinity is much higher in the intertidal zone because salt water trapped in rock pools evaporates leaving behind salt deposits. INTERTIDAL ADAPTATIONS Vertical Zonation • Highest zones >black lichen on highest zone >periwinkle zone (gastropods) >barnacle-dominated zone >zone dominated by different spp. (i.e. mussels in N. America) • Zone correlates with tidal levels (i.e. upper limit of seaweed) • Laminaria- extreme low water in sheltered areas
The intertidal zone is the area on a beach situated between the high tide and the low tide. This zone often includes more than one habitat, including wetlands and rocky cliffs. The intertidal zone provides habitat to a variety of animal species, such as mollusks, crustaceans, worms, some species of coral and algae.

A The Spray Zone B The High Tide ... Life in the Intertidal Zone. 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. The intertidal zone is the area on a beach situated between the high tide and the low tide. This zone often includes more than one habitat, including wetlands and rocky cliffs. The intertidal zone provides habitat to a variety of animal species, such as mollusks, crustaceans, worms, some species of coral and algae. intertidal zone, resulting in significant changes in habitat characteristics throughout the year. Species living in the intertidal environment have adapted in a variety of ways to survive these frequently changing conditions. Some move to follow the level of water as the tide rises and falls, or seek shelter in shaded crevices or beneath seaweed.
The Intertidal Zone Tides are caused by the gravity of the moon. The intertidal zone is the area that is exposed during low tide, and submerged during high tide. This union of lithosphere and hydrosphere results in wide range of plants and animals, each adapted to this environment.
to the intertidal zone. In most states, private owners hold title to the high-water mark and the states hold the inter-tidal zone, submerged lands, and coastal waters as trustees for the benefit of the public. This is known as the “Public Trust Doctrine” a lega, l principle that dates back centuries to The algae that exist in the intertidal species are very important to other organisms that inhabits the intertidal zone. Some of these algal species protect other organisms from desiccation from the sun and other harsh weathers. Below is a description of some algal species found in the intertidal zone and an example of a species from the ... High Intertidal Zone. 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. Mid Intertidal Zone. The middle intertidal zone is generally submerged, except for a period during the ...
