When covered by the rising tide the shore life really comes to life and snorkelling is an excellent way to see the marine life of the shallows. Seaweeds buoyed up by the water, wave in the swell. Limpets and winkles crawl about, grazing in earnest before the falling tide forces them to close up once more. Barnacles and anemones open up to exploit the food-bearing water while fish and crabs hunt around for tasty titbits.
