This book is a richly illustrated natural history of the world’s crabs, examining their diversity, ecology, anatomy, behavior, and more. With over 7,000 species in 100 families, crabs are one of the most diverse and adaptable animal groups. They thrive in various environments, from abyssal seas to tropical rainforests. Crabs play a vital role in marine and coastal ecology, making them keystone species in habitats like coral reefs and coastal swamps. The book comprises five chapters: evolutionary pathways, anatomy and physiology, ecology, reproduction, cognition, and behavior, and exploitation and conservation. Each chapter includes subtopics, exceptional images, and double full-page species profiles. These profiles highlight remarkable aspects of the life of these fascinating creatures. (This book may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
