Guide to the Manta and Devil Rays of the World

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.
