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.
Students could be asked to consider the difficulties creatures face living in the rock pool habitat, and how they have adapted to survive. They could draw a labelled diagram of some of the creatures living here, and annotate to describe their physical and behavioural characteristics that help to ensure their survival in this environment. This idea could then be applied to other animals in other habitats. Students could then create a creature to survive in a theoretical habitat, explaining the key characteristics about their creature that enable it to survive there.
