During a light rain, a child dozes on a sandy ocean-side beach, snuggling in her mother’s arms. But while the sand beneath her is soft and still, there’s a whirlwind of activity in the sea next to her. The waves roll back and forth to shore, while beneath them a busy underwater world is teeming with life. As the girl sleeps, she dreams of participating in that world.

Through lyrical text, award-winning science writer Suzanne Slade (June Almeida, Virus Detective! The Woman Who Discovered the First Human Coronavirus) takes young readers on an exploration of our oceans and the many creatures and ecosystems found there, from migrating whales to elusive eels to the colorful coral reefs.

Back matter includes science facts, as well as a reminder of why we need to be good stewards of the world’s oceans. This companion title to The Universe and You illustrates once again that our natural world is full of wonders just waiting to be explored.
