The book offers a guided, illustrated tour of shore life for young readers, pairing forty-eight coloured plates with concise descriptions of fishes, molluscs, bivalves, crabs, lobsters and kin, sea worms, starfish, anemones, corals, sponges, and seaweeds. It emphasizes simple observational techniques—how to search rock pools, recognise nests and shells, and note behaviour and habitats—while explaining basic anatomy, life cycles, and collecting tips in child-friendly language. Each chapter names common shore organisms, highlights distinctive features and habits, and encourages careful looking to make seaside visits more instructive and enjoyable.
