Many of the seals and sea lions that people are familiar with are appealing, cute animals, but no one is likely to use those words to describe male elephant seals. These enormous "elephants of the sea" have an inflatable trunk-like proboscis they use to produce booming noises that can be heard miles away. Engaged readers will learn this and more about the lives of these remarkable animals. Accessible text addresses important science concepts, while lively images dazzle the eyes. Fact boxes and a graphic organizer enhance the narrative.
