Little ones can swim along with a baby bottlenose dolphin and experience a day in his life — diving, chasing and exploring his underwater world — in “Dolphins,” a new children’s picture book by Rebecca Heller and illustrated by Suzie Mason.

The 12-page board book, ideal for early readers, includes 15 fun facts to educate children about these mesmerizing mammals. (Did you know female dolphins are called cows, males are called bulls and babies are called calves? And that there are more than 40 dolphin species in the world?)

Heller, a Los Angeles-based author and avid surfer with family in Hawaii, has written several books based on her love of animals and the ocean. Mason is a New York Times best-selling illustrator who has filled the charming picture book with beautiful, vibrant artwork of aquatic life. The book “is dedicated to all those who work to keep dolphins wild and free.”
