"This fully illustrated guide is designed to assist with the identification of a selection of deep-sea cartilaginous fishes of the Indian Ocean that are of major, moderate or minor importance to fisheries. ... 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.

"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 Indian Ocean. It includes 10 orders, 23 families, 45 genera, and 78 species of cartilaginous fishes, providing accounts for all orders, families and genera, and all keys to taxa are fully illustrated.

This comprehensive guide encompasses a total of 473 species of mesopelagic fishes (i.e. those fishes residing primarily between 200 and 1 000 m depth during daytime) that are known to occur in the western Indian Ocean. It aids in their accurate identification, offering dichotomous keys to all taxa. 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. Captions and arrows enhance user-friendliness for to both specialists and non-specialists in the field of ichthyology. In the broader context of marine ecology, mesopelagic fishes hold a pivotal role as integral components of the marine food web, serving both as predators and prey for various species. This guide not only enriches our understanding of these fishes but also contributes to our knowledge of the western Indian Ocean's diverse ecosystem. Beyond species identification, it sheds light on the interconnectedness of marine life and underscores the importance of conservation efforts in safeguarding this delicate balance. This guide serves as an invaluable resource for in-depth exploration and research into these remarkable fishes, offering a comprehensive tool for studying their diverse characteristics, behaviours, and ecological significance, essential elements for sustainable management and conservation practices.
