Book excerpt: A Whale’s World follows a pod of spy-hopping orcas as they explore the ecosystems of the Great Bear Sea while hunting for their next meal. Past rocky shores and through kelp forests, they observe foraging wolves, hungry grizzly bears, curious black bears, graceful fin whales, splashing porpoises, slippery seals and other members of the Pacific coastal food web. The book gives readers a fun introduction to the many ways that marine and land animals interact with their environments and with each other.
