It is intended that this shall be one of a series of papers of similar scope dealing with the fauna of Monterey Bay, with a view toward placing at the disposal of workers at the Marine Biological Laboratory an easy means of becoming acquainted with the invertebrates of that region. Preliminary work has been done in several groups, and in the case of the Anomura and the Macrura, the writer hopes to present reports in the near future. Monterey Bay occupies an open semicircular indentation of the coast line, a little over one hundred miles south of San Francisco, measuring about twenty-five miles from Santa Cruz on the north to Point Pinos on the south, and perhaps ten miles from a line drawn between these two points to the mouth of the Salinas River on the east. The northern and eastern shores of the bay are low and sandy, but from a point near the town of Monterey to Point Pinos and thence south nearly to the town of Carmel, some ten miles, the coast is, with the exception of a few small sandy beaches, extremely rugged, furnishing innumerable rocky tide-pools that form an unusually rich collecting ground, not only for Crustacea but for all kinds of invertebrates. The Stanford Marine Biological Laboratory is located at Pacific Grove, about midway of the southern shore of the bay, and as this has been the central point for shore collecting, the greater part of the work has been confined to four or five miles of the coast, reaching from near Monterey to some distance south of Point Pinos, though a few trips have been made to points north or south of these limits. Considerable dredging has been done at moderate depths, thirty fathoms and under, from a small launch. Off the eastern shore the bottom is sandy; this has been little worked, but has yielded some valuable specimens. Off the town of Monterey in the southeastern corner of the bay there is a large area of hard blue clay, rich in burrowing mollusks, which has proved a good field for Crustacea, and here most of the dredging has been done.

DOWNLOAD EBOOK →This book introduces updated information on conservation issues, providing an overview of what is needed to advance the global conservation of freshwater decapods such as freshwater crabs, crayfish, and shrimps. Biodiversity loss in general is highest in organisms that depend on intact freshwater habitats, because freshwater ecosystems worldwide are suffering intense threats from multiple sources. Our understanding of the number and location of threatened species of decapods, and of the nature of their extinction threats has improved greatly in recent years, and has enabled the development of species conservation strategies. This volume focuses on saving threatened species from extinction, and emphasizes the importance of the successful implementation of conservation action plans through cooperation between scientists, conservationists, educators, funding agencies, policy makers, and conservation agencies.
