"This fully illustrated guide is designed to assist with the identification of a selection of deep-sea cartilaginous fishes of the Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42'E to 30°00'E (FAO Fishing Area 47), that are of major, moderate or minor importance to fisheries. In this region, the deep--sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught. Each species is described, depicted with a colour illustration and photo, and key distinguishing features of similar-looking species occurring in the same area are highlighted allowing for easy and accurate identification in the field. Keys to the shark and batoid orders and families, together with keys to chimaera and skate genera are also provided. This guide is intended to help fishery workers collecting catch data in the field in the identification of the cartilaginous fish species they might encounter. It is conceived to be updatable, offering the possibility to add new species accounts as new species are described."--Publisher's description.

This guide includes a selection of species of relevance to fisheries as well as species that may be of research, educational and ecological importance. The Indian Ocean deep-sea chondrichthyan fauna is currently represented by 117 shark, 61 batoid and 17 chimaera species. This guide includes full species accounts for 36 shark species selected as being the more difficult to identify and/or commonly caught.

This volume is a comprehensive, fully illustrated Catalogue of the Sharks, Batoid Fishes, and Chimaeras of the Southeastern Atlantic Ocean, encompassing FAO Fishing Area 47. The present volume includes 10 orders, 23 families, 45 genera, and 78 species of cartilaginous fishes occurring in the Southeastern Atlantic. It provides accounts for all orders, families, and genera and all keys to taxa are fully illustrated. A species representative account of each genus is also provided and includes: valid modern names and original citation of the species; synonyms; the English, French, and Spanish FAO names for the species: a lateral view and often other useful illustrations; field marks; diagnostic features; distribution, including a GIS map; habitat; biology; size; interest to fisheries and human impact; local names when available; a remarks sections; and literature. The volume is fully indexed and also includes sections on terminology and measurements, an extensive glossary, and a dedicated bibliography.

This volume is a comprehensive, fully illustrated Catalogue of the Sharks, Batoid Fishes, and Chimaeras of the southeastern Pacific Ocean, encompassing FAO Fishing Area 87. The present volume includes 8 orders, 17 families, 39 genera, and 66 species of cartilaginous fishes occurring in the southeastern Pacific Ocean. It provides accounts for all orders, families, genera and species, and all keys to taxa are fully illustrated

This identification guide includes 552 species of mesopelagic fishes (i.e. those fishes residing primarily between 200-1000 m depth during daytime) that are known to occur in the central and south east Atlantic Ocean. Fully illustrated dichotomous keys to all taxa are provided. Species are treated in detail, with accounts including the scientific name, FAO common name in English (where available), other useful characters, size, a distribution map, and one or more illustrations. To facilitate even further the identification of the taxa, captions and arrows are added to help users quickly locate their key morphological features. The guide is intended for both specialists, and nonspecialists who have a working knowledge of ichthyology.
