Over 50,000 living species have been named, making molluscasecond only to the Phylum Arthropoda in number of species known. http://animaldiversity.ummz.umich.edu/mollusca.html

The University of Michigan Museum of Zoology Animal Diversity Web About us ... Glossary Phylum Mollusca 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.

MEER home Marine biology home Table of Contents Index ... Links Phylum Mollusca 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.

Molluscan Evolution 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.

Metazoan Diversity/ Phylum Mollusca Graham Davison Bsc Zoology Phylum Mollusca Metazoan Diversity Home/ Extinction and Biodiversity Homepage/ Origins and Evolutionary Relationships/ Molluscan diversity ... References 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
