Decapods are a culmination of nearly 600 million years of Crustacean evolution, during which time they have radiated into a variety of superfamilies, families, genera and species which occupy a variety of niches from fresh mountain streams to the abysses of the oceans. This book will fill a gap in the current literature on southern African decapods. Since Barnard published his Descriptive Catalogue of South African Decapod Crustacea in 1950, there have been numerous additions and name changes. This publication updates the taxonomy, and includes ecological and fisheries information. In addition, Kensley’s (1981) distributional checklist for the region has been updated and includes large numbers of new species and records for the region, bringing the total number of decapod to over 1000 species. Although not exhaustive, 262 species are featured, some of which are beautiful, some have commercial or artisinal value, both for consumption and the aquarium, and some have important ecological functions, while others are rare or interesting. For each species there is a photograph, synonymies, common names, a description, ecological information and name derivation (etymology). All the decapod families found in South Africa are described, some new, along with chapters on decapod research history in southern Africa, commercial and artisinal food value of decapods, biodiversity and future research direction. The book is arranged systematically, as taxonomy is based on phylogeny, starting with the earliest forms and progressing to the most derived and advanced forms, and will serve to stimulate interest and future research into southern Africa’s rich decapod biodiversity, especially at a time when biodiversity itself is threatened by global warming, coral bleaching and habitat loss. It will appeal to people interested in Decapoda, including academics, scholars, students, fishermen, aquarists, aquaculturists, recreational snorkel and SCUBA divers, as well as those interested in conservation, biodiversity, management and governance.
