A children’s colouring and activity book that teaches basic marine ecology concepts—including tidal cycles, predator-and-prey relationships, food chains, habitat, and conservation—through detailed illustrations and informative text.

High Tide, Low Tide is a fun and captivating introduction to the great variety of marine life that can be found at the seashore. With ready-to-colour pictures on nearly every page, along with a list of common species names and a colour key, this book will teach children to identify snails, sea stars, hermit crabs, shore crabs, mussels, barnacles, tidepool sculpins, sea anemones, sea urchins, giant octopuses, shorebirds, harbour seals, seaweeds, and more. The clear, informative text describes basic concepts about how animals and plants live together and survive the always-changing marine environment at different stages of the tidal cycle. While educators and parents will find this book an effective tool for teaching science, reading, critical thinking, observation skills, and basic concepts in conservation, kids will enjoy hours of colouring fun and fascinating facts.
