* Reviews *
Although designed for reluctant readers, this book is delightful enough to appeal to anyone interested in whales, dolphins, and seals. Researchers have devised clever experiments and created equipment that allows them to video and learn new information about these fascinating creatures. A simple demonstration is described to help students understand the ability of dolphins to dive and remain underwater so long. Researchers devised experiments that showed that baby whales and dolphins don't sleep for their first month, nor do their mothers. Scientists watched mother dolphins teach their young to use sponges to scour the sea bottom for food, and they learned how seals use whiskers and air bubbles to help catch their prey. The layout is attractive with numerous photos and fact summaries explaining more about these intriguing creatures. Curious readers can easily find additional information on the Internet.
