Crabs on the Beach [PDF ebook] 

Crabs are amazing sea creatures. They scuttle sideways across the sand and breathe underwater using gills. If a crab loses a claw, it can regrow it. This book provides readers with an up-close look at what life is like for crabs on the beach. Important life-science topics, including habitat and life cycle, are covered in rich detail. Beautiful full-color images and manageable text foster reading comprehension skills. Fact boxes provide readers with information about crabs on each page.
