Manta and devil rays are some of the most intriguing creatures in the ocean. Driven forward by powerful beats of wing-like pectoral fins, these filter feeders search the waters for prey, their horn-like head fins giving rise to ancient mariners’ tales of fearsome devilfish dragging boats into the ocean 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 species in this family. Illustrated with more than 200 color photos, drawings, and plates, this guide also contains an expansive introduction to the general taxonomy, biology, and behavior of these iconic animals. This book will be an essential resource for fisheries management and international trade enforcement, and for anyone involved in ongoing manta and devil ray research and conservation.

  • The first dedicated field guide for manta and devil rays
  • Exhaustive treatment of every aspect related to their identification and biology
  • Filled with 200+ color drawings, photos, and diagrams
