This delightfully visual book, written by Martha & Ann Driscoll and illustrated by award-winning illustrator Susan Andra Lion, is packed with fascinating details about seahorses. The book answers the question - is a seahorse a fish or is it a horse? It's a fish, of course! In the book, Sammy the Seahorse and Lily the Lobster take the reader under the ocean and into the coral reef to learn about seahorses and their habitats. Included is educational information about a variety of seahorse species; unique characteristics of seahorses, seahorse habitats, anatomy, reproduction, threats to survival, and preservation. The book includes a hidden picture activity; colorful comparison of 25 kinds of seahorses; a challenge to readers to find all the seahorses, leafy sea dragons and pipefish tucked away inside the covers; and a detailed glossary of terms and reference information. Not a story book, but a fun and fascinating educational book that readers of all ages will enjoy.
