The authors are two of the best taxonomic experts in crustacean decapods, who have established the actual taxonomy and systematic of numerous and important groups of decapods. They have introduced new views and approaches on the taxonomy, phylogeny and biogeography of these crustaceans. This international edition adds diagnoses and identification keys to all world families and genera: this information simply doesn't exist in any other book. During the last decade, the world register of marine species (WORMS) has created the list of known species and promoted the publication of numerous compilations on crustacean decapods. However, except specialists of each taxa, very few colleagues can identify correctly the new families and genera - there are no keys to these new groups. This book is the first to contain these world keys and is therefore a life rope for students, marine biologists, taxonomists and naturalists. The mixture of taxonomic line drawings, color illustrations and images of real-life specimens is extremely helpful for identification, especially when working in the field.
