Book Description
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

Rays of the World

Author: Peter Last
Publisher: CSIRO PUBLISHING
ISBN: 0643109145
Category : Science
Languages : en
Pages : 801

Book Description
Rays are among the largest fishes and evolved from shark-like ancestors nearly 200 million years ago. They share with sharks many life history traits: all species are carnivores or scavengers; all reproduce by internal fertilisation; and all have similar morphological and anatomical characteristics, such as skeletons built of cartilage. Rays of the World is the first complete pictorial atlas of the world’s ray fauna and includes information on many species only recently discovered by scientists while undertaking research for the book. It includes all 26 families and 633 valid named species of rays, but additional undescribed species exist for many groups. Rays of the World features a unique collection of paintings of all living species by Australian natural history artist Lindsay Marshall, compiled as part of a multinational research initiative, the Chondrichthyan Tree of Life Project. Images sourced from around the planet were used by the artist to illustrate the fauna. This comprehensive overview of the world’s ray fauna summarises information such as general identifying features and distributional information about these iconic, but surprisingly poorly known, fishes. It will enable readers to gain a better understanding of the rich diversity of rays and promote wider public interest in the group. Rays of the World is an ideal reference for a wide range of readers, including conservationists, fishery managers, scientists, fishers, divers, students and book collectors.

Elasmobranch Biodiversity, Conservation and Management

Author: Sarah L. Fowler
Publisher: IUCN
ISBN: 9782831706504
Category : Business & Economics
Languages : en
Pages : 282

Book Description
The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.
