Sperm Whales

By Janet Perry and Victor Gentle

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.Sperm whales have the biggest brains on the planet, but that was not enough to protect them from whalers in the past -- and even the present in some countries. The large head of the sperm whale is filled with liquid wax and fat, both used in echolocation. Learn about the clicks, creaks, and clangs that sperm whales use to see in the deep, dark ocean and about the giant squid it crunches in its huge teeth. Lively text accompanied by large photos explain the sperm whale's habits and structure and the threats to its survival.
