{ "item_title" : "Hagfish Handbook", "item_author" : [" Raphael Walker "], "item_description" : "This comprehensive Hagfish Handbook is a professional and scientifically rigorous exploration of one of Earth's most ancient and intriguing vertebrates. It synthesizes the latest research across multiple disciplines-evolutionary biology, deep-sea ecology, materials science, and conservation policy-to present hagfishes as more than just a biological curiosity.Beginning with their evolutionary origins, the book traces the lineage of hagfishes back more than 500 million years, explaining their crucial role in illuminating the early steps of vertebrate evolution. Detailed chapters explore their unique anatomy and physiology-from the persistent notochord and keratinous tooth plates to the legendary defensive slime that rivals spider silk in strength and inspires next-generation biomimetic materials.Readers are guided through the ecological significance of hagfishes as key scavengers in the deep sea, where they accelerate nutrient recycling and influence global carbon cycling. The text then examines their interactions with humans, including the global eel-skin leather trade, the socio-economic value of hagfish fisheries, and the ethical and legal considerations of harvesting these slow-reproducing animals.Looking toward the future, the handbook surveys emerging research frontiers, from genomics and evolutionary developmental biology to CRISPR-based genetic studies and cutting-edge biomaterials engineering. It also provides practical guidelines for captive husbandry and laboratory research, offering detailed insight into maintaining these deep-sea organisms in controlled environments for behavioral and physiological studies.Written in a professional, educational style, this book appeals to marine biologists, evolutionary scientists, materials engineers, conservationists, and advanced students alike. It bridges fundamental science and applied technology, demonstrating how the study of a seemingly obscure deep-sea creature can transform our understanding of vertebrate origins, support sustainable ocean management, and inspire innovative solutions in biotechnology and materials science.More than a natural history, the Hagfish Handbook is a global perspective on science and sustainability, showing how one ancient lineage can connect Earth's evolutionary past with the technological and ecological challenges of the twenty-first century.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/826/571/9798265718853_b.jpg", "price_data" : { "retail_price" : "13.30", "online_price" : "13.30", "our_price" : "13.30", "club_price" : "13.30", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
