"Did you know humpback whales have lungs and need to reach the ocean surface in order to breathe? The humpback whale turns off half of its brain in order to sleep, while the other half stays awake to control the whale's breathing. Discover more about this intriguing underwater dweller in Humpback Whales, a Giants of the Ocean book."--
