Coastal habitats are the places where the land meets the ocean. They can have rocky cliff edges, sandy beaches and rock pools. Most marine life lives in coastal habitats.

Ocean habitats are large and wet. Some ocean habitats are shallow, sunny and warm and others are deep, dark and cold. They are hotter near the equator and colder near the North and South Pole. This means that the conditions are different in the different areas of the oceans so different animals are suited to living there.
