Lower intertidal zone
Below the bed of mussels lies the lower intertidal zone, which is dominated by seaweeds. The red seaweed commonly known as Irish moss (Chondrus crispus) grows like a thick carpet over the rocks in this zone. When the tide is low, spaces between the rocks retain water, forming small habitats known as tide pools . Tide pools are like natural aquarium tanks that contain algae, invertebrates (such as snails and crabs), and small fish. |
