Hardy adventurers ages 6 - 9 dive into a silent watery world where tiny coral animals grow together to form rock gardens of white, pink, and red-orange. In this action-packed undersea circus, jaws snap, tentacles sting, ink gets squirted, and fish suddenly glow while animals that look like plants sway gently and bashful clams hide the lively secrets inside their shells. Surprisingly dry and armed with a few pieces of equipment and their boundless imaginations, children explore this magical realm one small square at a time. Science education at its best. - Science Books and Films
