The mysterious lives of whales and dolphins come alive in the full-page photos and lively text of the Whales and Dolphins series. Explore the unique behavioral and physical adaptations that allow these sea mammals to swim fast, leap above the water, blow loud exhale blasts, create curious clicks and clangs or haunting songs, and use echolocation to see in deep, dark waters. Humans feel a connection to these intelligent, playful fellow mammals, and the more we learn about their communication, group lives, and devotion to their calves, the closer that connection becomes. Surprising facts, bold images, and detailed narratives will satisfy curious young readers of Whales and Dolphins.Due to overhunting, only about 10,000 humpback whales live in the world's oceans. Learn how humpbacks squirt water through their baleen to trap the krill they eat, and join the humpback's four-thousand-mile migration between the northern and southern hemispheres. Full-page photos show humpback whales blowing bubbles, protecting their calves, and leaping out of the water. Engaging text includes explanations of regional variations among these whales and how human pollution may threaten the humpbacks that remain.
