Head to the depths of the ocean to study humpback whales.

You may know that humpback whales use whale song to communicate with each other, but there’s so much more to discover about these giants of the sea! Dr. Asha de Vos explains how humpbacks use special bubble nets to catch fish, and what makes them sometimes launch themselves high out of the water.

This book also explains how hunting made humpback whales an endangered species—and how conservation efforts have seen their numbers increase again.
