Extractions: The University of Michigan Museum of Zoology Animal Diversity Web About us ... Glossary Molluscs are bilaterally symmetrical eumetazoans. They have a true coelom (eucoelom) which is formed by the splitting of embryonic mesodermal masses (schizocoely). Development is protostomous. An important characteristic of most molluscs is the head-foot region. Most molluscs are strongly cephalized; that is, they have a well-developed head, in which is located a mouth and a concentration of nervous and sensory functions. Adjacent to the head is a large, muscular foot formed from the ventral body wall. Used primarily in locomotion, the surface of the foot is sometimes ciliated and and laden with numerous mucous glands. Another characteristic of most molluscs is the mantle. This sheath of tissue is formed from the dorsal body wall. It surrounds the mantle cavity, which houses the gills or lungs if they are present, and its surface may assist in gas exchange. The mantle also secretes the shell in those forms that possess one. Internally, molluscs have a complicated digestive system, with a mouth in the head and the anus emptying into the mantle cavity. A rasping organ used in feeding, the radula, is present in all groups except bivalves and Aplacophora. The radula is usually toothed and its structure may be very complex. It is adapted to a wide variety of feeding styles in different species, including scraping, tearing, stabbing, and cutting.

Extractions: Tylodina fungina class Gastropoda, phylum Mollusca, modified from McFarland, 1966. The molluscs rival the arthropods in their diversity of body forms and sizes, as well as their ecological success. The phylum also provides some of the most familiar animals, such as snails clams mussels squids , and octopus (which, like the arthropods , are well known because they're good to eat). The phylum Mollusca also includes lesser known forms such as the chitons tusk shells, solenogasters , among others. Approximately 50,000 species of Molluscs have been described, and because of the shelled forms they have left a rich fossil record. However, the earliest molluscs probably arose in the Precambrian , and nothing is known about what they were like.

Extractions: Listserver Information Molluscs are one of the most diverse groups of invertebrate animals - both in form and habitat. They have figured prominently in paleobiological and biological studies, and have served as study organisms in numerous evolutionary, biomechanical, ecological, physiological, and behavioral studies. It is our intent to provide an informal and rapid response forum for discussions of molluscan evolution, paleontology, taxonomy and natural history. A special emphasis of this list server will be to provide an interface between paleontological and neonotological molluscan workers. We will also post notices of meetings, symposia, literature, software and other electronic happenings that may be of interest to the malacological community.

Systematic Research Collections: Mollusca
List of recent and fossil mollusca systematic research collections. Maintained by the Illinois Natural History Survey.
http://www.inhs.uiuc.edu/cbd/main/collections/mollusk_links/museumlist.html

Extractions: The following list of mollusk collections has been compiled to aid researchers by providing an up-to-date list of curators, collection managers and a description of the collection (i.e. size, geographic scope, percent computerized, etc.). Links have been added to each museum where additional information can sometimes be found. If a link is not present please send an url or gopher address to Kevin Cummings (ksc@mail.inhs.uiuc.edu ) and it will be added to the list. We would encourage any of the collections listed to provide a summary of their holdings or update an existing summary. We will date all new entries to provide a time reference to the information. Acronyms have been added to the list and have been taken from:

Extractions: Kimberella (adapted from Fedonkin and Waggoner, 1997). The mollusca are amongst the largest of all of the metazoan phyla, with approximately 50,000 described species, and an evolutionary history stretching back to the Pre-Cambrian period [Fedonkin and Waggoner, 1997]. A number of well preserved specimens of the fossil Kimberella have recently been excavated from Northern Russia, and depicted as a "mollusc-like bilaterian organism". If this identification is accurate it suggests that triploblastic protostome animals existed far earlier than previously assumed, and pushes back metazoan origins ( Link ) into the pre-Ediacaran period [Fedonkin and Waggoner, 1997]. Molluscs are characterised by the development of a coelom , or true body cavity. The coelom is a major advance over more primitive acoelomate and pseudocoelomate conditions, in that a
