With this edition, access to the texts of the famous Traité de Zoologie is now available to a worldwide readership. Parts 1, 2, and 3A of volume VII, i.e., the Crustacea, were published in French in, respectively, 1994, 1996, and 1999. Brill recognized the importance of these books and arranged for a translation to be made. However, some of the manuscripts dated from the early 1980s and it was clear from the beginning that in many fields of biology a mere translation of the existing text would not suffice. Thus, all chapters have been carefully reviewed, either by the original authors or by newly attracted specialists, and adequate updates have been prepared accordingly.

This second volume of The Crustacea, revised and updated from the Traité de Zoologie contains chapters on:
-The circulatory system
-The digestive tract: anatomy, physiology, and biochemistry
-Osmoregulation: morphological, physiological, biochemical, hormonal, and developmental aspects
-The endocrine organs
-The ontogeny of sex and sexual physiology
-The origins of crustacean larvae

The volume concludes with a list of contributors, as well as with both taxonomic and subject indices.
