Publisher's Synopsis
"What do crabs and lobsters have in common and how are they different? While both animals live in the ocean, one prefers to swim and the other to walk. One can be found in coastal tidepools and the other offshore. They both have skeletons on the outside of their bodies. There's more to these animals than just being good food for us. Learn about these fascinating crustaceans in this latest addition to the Compare and Contrast Series"--.
