A classroom favorite, this book provides a first glimpse of marine mammals that's ideal for budding oceanographers!

In this beginner's guide, author and educator Cathryn Sill simply and clearly shows children what is essential for understanding and appreciating marine mammals—how they look, how they move, what they eat, and where they live. She covers animals as diverse as whales and otters to dolphins, polar bears, and more.

The beautifully detailed, realistic paintings of noted wildlife illustrator John Sill depict a variety of marine mammals. An afterword provides more details for further exploration.
