A vibrant, illustrated guide to the mermaids and sea creatures living in the oceans, rivers, and streams (yes, really!) around the world. For centuries, sailors have told tales of majestic-sometimes dangerous-creatures lurking beneath the ocean waves. Over the years, however, researchers have traced these legends to the very real world of merfolk. From yemayas and morgen to sirens, frosties, and more, this illustrated compendium of mermaids takes a deeper look at the different species swimming in seas around the world and highlights their magical abilities. Complete with interactive quizzes (e.g. "What's Your Mermaid Personality?") and activities/crafts (e.g. Beachcombing: Identifying Fossils; Brew Your Own Ocean Potion), this field guide will sweep you away on an underwater adventure!
