An "illustrated guide to the incredible diversity of snakes around the world. Snakes are found on every continent except Antarctica and have evolved to occupy a vast range of habitats, from mountains to oceans and deserts to rain forests. Snakes of the World explores their extraordinary diversity, with an in-depth introduction covering anatomy, behavior, habitats, reproduction, conservation, and other essential topics. This expert guide also includes profiles of some of the approximately 4,000 species of snakes, featuring examples from every family and subfamily. Each family profile highlights the remarkable appearance, characteristics, and lifestyle of notable snake species. Covering how snakes use venom or constriction to subdue their prey, how a snake's appearance can aid camouflage or boast of its killing capacity, and how habitat destruction is jeopardizing the future of many species, Snakes of the World is an invaluable guide to these fascinating reptiles."--Back cover.

"Sharks have been fighting for their lives for 500 million years and are under dire threat today. They are the longest surviving vertebrate on Earth, outlasting multiple mass extinction events that decimated life on the planet. How did they thrive so long? By developing superpower-like abilities that allowed them to ascend to the top of the oceanic food chain. Yet they often found themselves in the shadows of larger, more formidable killers--and they not only survived, but also took their crown as the king of the sea. ... Because of recent technological breakthroughs, scientists' understanding of sharks has taken a quantum leap forward in the last decade. John Long has been on the cutting edge of this research and in this [book] weaves a fully updated and unexpected tale of shark's extraordinary evolutionary adventure"--

This book focuses specifically on environmental risk assessment in premetamorphic stages and adults of amphibians and is an ideal companion for toxicologists and ecologists also of interest to those working in conservation biology, biological invasion, biocontrol and habitat management.

Catfish, one of the largest groups of freshwater fishes, are not only important ornamentals and sport fishing and research animals but also an important source of protein. This book compiles current research on this species, providing information on its production methods and uses.

In this groundbreaking work Anthonie Cornelis Oudemans, explores the mysterious and elusive creature known as the great sea-serpent. Originally published in 1892, this book remains one of the most comprehensive and well-researched studies of sea serpents to date. Oudemans became immensely fascinated by this often enormous creature, and spent three years of intensive research before publishing his work.He argues for the existence of a sea-serpent that can grow up to 60 feet long, which, according to the many recorded sightings, often resembles a prehistoric Plesiosaur. Oudemans relied on nearly 200 eyewitness accounts and many publications, and named the creature Megophias Megophias in Latin, in accordance with scientific convention. However, Oudemans' colleagues did not approve of his work on sea monsters, as they believed such creatures could not exist. Despite this, his work gained recognition posthumously. In the 1950s, Belgian biologist Bernard Heuvelmans rediscovered Oudemans' work and found in his sea-serpent the missing link in cryptozoology.This new revised edition features a clear distinction between Oudemans' ongoing text and the many included eyewitness accounts, as well as all original images that have been cleaned up for clarity. Additionally, readers will find a Post Scriptum containing biographical information about the author and - as a bonus - the first English translation of Oudemans' original 1934 Dutch-language essay on the Loch Ness Monster.WITH 82 ILLUSTRATIONS

A personal story of how amphibian conservation and research has developed in Britain since the late 1960s by someone who was there right at the beginning. The author initiated key long-term monitoring, surveillance and studies that continued until well into this century.
