Underwater forests of kelp, armor-plated barnacles, flower-like sea anemones, spiny sea urchins, and swooping gulls all live together in a tide pool. This book would be a good student reference for 4th graders studying the bottom dwellers of a kelp forest as well as a good resource for teachers focused on the 1st grade rocky seashore curriculum. Descriptions of the ecological relationships of the different plants and animals that live in low, mid, and high-tidal zones.
