Intertidal Zone Organisms and Adaptations

The video explores the intertidal zones at Olympic National Park, explaining the meaning of intertidal, the impact of tides, and the unique habitats formed. It highlights the issue of plastic pollution, particularly nurdles, and the importance of conservation efforts. The video also examines the vertical zonation of organisms in high, mid, and low intertidal zones, detailing the different species found in each zone and their adaptations to air and water exposure.

What does the term 'intertidal' refer to?

• A specific type of seaweed

• A type of marine organism

• The area between high and low tides

What is the role of coralline algae in the low intertidal zone?

• It is a primary food source for limpets

• It is used by anemones for camouflage
