Asian Horseshoe Crabs: Biology, Ecology, Conservation, and Utilization provides a comprehensive and updated look at horseshoe crabs, often dubbed “living fossils.” Overfishing and environmental pressures have endangered these crustaceans, making this book essential for their protection. Authored by international experts, it focuses on three species: Tachypleus tridentatus, Tachypleus gigas, and Carcinoscorpius rotundicauda, covering their evolution, reproduction, physiology, and behaviors. Moreover, the book delves into the genomics and population dynamics of horseshoe crabs, examining their significance in human consumption and biomedical research, and including the use of blue blood and chitin. Conservation efforts and practices are also discussed, making this book a valuable resource for marine biologists, students, and academics.
