Publisher's Synopsis
"Everyone loves to watch playful sea otters frolicking in coastal waters. But did you know that the kelp forests where they live depend on otters for their survival? Otters are a keystone predator. They prey on sea urchins that would otherwise destroy the habitat that shelters so many other species. This book explains the concept of keystone species in easy-to-understand language. Beautiful full color photographs introduce the watery world of the kelp forests and fun fact boxes break down complex ideas"--.
