Creatures living in a coastal rockpool must adapt to the water being heated by sunlight and diluted by rainwater, as well as to the water levels dropping. In a rockpool at the coast we are introduced to an anemone. Anemones are animals which are found all along the shoreline. Their tentacles have hooks on the end for capturing animals which they eat. When the tide is in, limpets and periwinkles eat algae on the rocks. Periwinkles also eat seaweed.
Children could be asked to watch the clip and consider what difficulties creatures face living in the rock pool habitat, and how they have adapted to survive. This idea could then be applied to other animals in other habitats. The children could then create a creature to survive in a theoretical habitat, explaining the key characteristics about their creature enabling it to survive there.
