This practical field guide, published in association with the Wildlife Trusts, includes nearly 180 species that live in the area between land and sea called the intertidal, or littoral, zone. Home to plants and animals that are usually very different in form from their land-based relatives, the seashore is unlike any terrestrial habitat. This guide includes all the most common molluscs, crustaceans, seaweeds, fishes, spiny creatures such as starfishes and sea urchins, mammals and many other species found here, and is invaluable for anyone wanting to find out more about the fascinating shells and other objects they may pick up on our shores. Each species account includes accurate artworks and a concise written account that covers essential details such as size, general description, habitat, ecology, and distribution in Britain and the near Continent. The easy-to-follow layouts and illustrations aid quick and precise identification, making this book an indispensable reference in the field as well as at home.
