Life in the Intertidal Zone. It is inhabited by hardy sea life that can withstand pounding waves, such as barnacles, marine snails, mussels, limpets, shore crabs, and hermit crabs. For example, a temperate rocky intertidal region will have quite different flora and fauna when compared to a mangrove intertidal zone. The intertidal zone is a critical interface between terrestrial and marine ecosystems. This barnacle is found in association with the California mussel. The organisms in this zone vary, but in greater quantity. At the top of the intertidal zone, organisms spend more time exposed than underwater, so they will have to cope with desiccation and large temperature swings. Goose barnacle (Pollicipes polymerus) Goose barnacles have gooseneck-like flexible stalks, and can withstand pounding surf. They are found on open ocean coasts in intertidal areas. the lower intertidal zone. above the high tide mark in the splash zone, is almost always dry, organisms wet by wave splash and spray only middle intertidal submerged and uncovered by tides regularly, variations in immersion time In this region, characterized by mixed semi-diurnal tides (two high and low tides in 24hr, of unequal size), the ebb and flow of the tide determines the rhythm of life cycles and behaviours of many animals, both marine and terrestrial (including people!
