Book Description
Crustaceans that are now called copepods have been known, not necessarily by that name, since Aristotle. Published reports of their post-embryonic development, however, date only from the last 250 years. This monograph is a first attempt to gather all published information about copepod post-embryonic development. Careful diagnoses of nauplius and copepodid allow comparisons of specific developmental stages among species. Changes from the last naupliar stage to the first copepodid stage are used to interpret the naupliar body. Body and limb patterning are discussed, and models of limb patterning are used to generate segment homologies for the protopod and both rami. Contributions of post-embryonic development to phylogenetic hypotheses are considered and suggestions for future studies are provided.

Book Description
An illustrated guide to the sweeping diversity of crustacean larval forms. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL Crustaceans—familiar to the average person as shrimp, lobsters, crabs, krill, barnacles, and their many relatives—are easily one of the most important and diverse groups of marine life. Poorly understood, they are among the most numerous invertebrates on earth. Most crustaceans start life as eggs and move through a variety of morphological phases prior to maturity. In Atlas of Crustacean Larvae, more than 45 of the world's leading crustacean researchers explain and illustrate the beauty and complexity of the many larval life stages. Revealing shapes that are reminiscent of aliens from other worlds—often with bizarre modifications for a planktonic life or for parasitization, including (in some cases) bulging eyes, enormous spines, and aids for flotation and swimming—the abundant illustrations and photographs show the detail of each morphological stage and allow for quick comparisons. The diversity is immediately apparent in the illustrations: spikes that deter predators occur on some larvae, while others bear unique specializations not seen elsewhere, and still others appear as miniature versions of the adults. Small differences in anatomy are shown to be suited to the behaviors and survival mechanisms of each species. Destined to become a key reference for specialists and students and a treasured book for anyone who wishes to understand "the invertebrate backbone of marine ecosystems," Atlas of Crustacean Larvae belongs on the shelf of every serious marine biologist.

Book Description
Specimens of new Harpacticoida species were obtained during the California Outer Continental Shelf (OCS), Phase II, Monitoring Program (CAMP) between November 1986 and May 1989. The CAMP project was a multidisciplinary study to detect and evaluate the long-term biological impacts of continental shelf oil drilling and production. The study was centered around a proposed platform site named Julius, which was never put into service. Samples were collected in the Santa Maria Basin on a regional scale (10- 20 km). Harpacticoids are the second most abundant meiofaunal taxa in the Santa Maria Basin. Harpacticoids have been intensively studied in the Atlantic OCS. However, Pacific studies are limited to collections made in shallow water. There are a great number of undescribed species in the CAMP samples taken from the Santa Maria Basin. The present study is rather limited in scope and only touches on some of the dominate species found. It contains full taxonomic descriptions of six species, a pictorial key of 18 dominant species, and drawings of 42 other unknown species.
