Animals Without Backbones

by Elaine Pascoe

What does it mean not to have a backbone? How can you tell an arthropod from a worm? This book focuses on the many and varied creatures of the animal kingdom that get along quite well without a spinal chord. Echinoderms, arthropods, and mollusks are some of the groups described and beautifully photographed.
