Bubble Homes and Fish Farts

"Bubbles are soft and squishy and full of air. They shimmer. They fl oat. And they are very handy." Bubbles serve many different functions for a wide variety of animals. Some use them for protection, some to find food, and others to keep warm. Violet sea snails sail along the ocean surface on rafts made of bubbles. Herring use bubbles to communicate, and water spiders even live in bubbles. End notes about each animal. Combined glossary and index. Full-color watercolor illustrations.
