Fun Facts
Glaciers deposited the rocks.
Animals that live in the intertidal zone have to adapt so that they can live on land and in the water.
They have hard shells to protect them from both drying out in the sun and the pounding waves.
Animals that live in the intertidal zone hold onto the rocks when the tide flows in and out. Snails stick to the rocks with suction. Mussels use adhesive byssal threads. Crabs clutch the rocks with their legs.
