Cathryn and John Sill explore slimy snails, clams, and more in their award-winning beginner’s guide to mollusks, a volume from the acclaimed About… series created by author and educator Cathryn Sill.

The book uses simple, easy-to-understand language to teach children what mollusks are, how they look, how they move, what they eat, and where they live.

The beautifully detailed, realistic paintings of noted wildlife illustrator John Sill introduce readers to a variety of mollusks-from the small garden snail to the giant Pacific octopus. An afterword provides more details about the animals in the book.
