This guide contains over a dozen ways to assist you with the identification of manta and devil rays and the species they associate with, whether in the ocean (alive), at fishery landings sites (dead), within trade (gill plates), or from the air. A new dichotomous key has been created to simplify identification using easy-to-recognise features. The key directs the reader to key identification characteristics, and to further aid and simplify identification, the guide and key colour codes the species by ocean-basin occurrence. Detailed species accounts provide key features, range maps, colour illustrations, behavioural descriptions and underwater imagery for each manta and devil ray species. This guide also provides the tools, guidance, and materials in the form of data collection protocols, codes of conduct, guidelines and more, which we hope will aid the research and conservation management of these threatened rays.

Manta and devil rays are some of the most charismatic creatures in the ocean. Born into a life of perpetual motion, these rays must keep swimming to survive. Driven forward by powerful beats of their wing-like pectoral fins, these filter feeding rays search the ocean currents for prey, their horn-like cephalic (head) fins giving rise to ancient mariners' tales of fearsome devilfish dragging boats into the depths. Beloved by scuba divers and marine biologists alike, these impressive animals have never had a comprehensive field guide dedicated to them until now. Guide to the Manta and Devil Rays of the World includes detailed information on the identification, characteristics, threats and distribution for each of the species within this family of rays. Illustrated with over 200 beautiful colour photos, drawings and plates, this guide also contains an expansive introduction packed full of useful information on the general taxonomy, biology and behaviour of these iconic animals. This book will be an invaluable field companion for any scientist, diver or marine enthusiast who has an interest in these fascinating creatures. It is an essential resource for fisheries management, international trade enforcement, and for anyone wanting to become involved in the ongoing efforts to research and conserve this threatened family of rays. 144 pp., full color, br. with gatefolds gr. 8 [215 mm x 171 mm].
