Seawater pools

These shores are affected by tides, becoming exposed to air and the sun when the water level drops. Rock pools are common in these areas, retaining water as the tide recedes. Seawater animals left exposed on dry rock as the tide falls, such as periwinkles, resist drying out by retreating inside their shells or by moving into shaded crevices.

Many plants and animals inhabit rock pools that trap water as the tide goes out. Water temperatures in these rock pools rise as they are warmed by the sun and cool during the night. Therefore organisms that live in these pools must also cope with these changes in temperature. ....................................................................
