One of the grand divisions of the animal kingdom, including the classes Cephalopoda, Gastropoda, PteropodaScaphopoda, and Lamellibranchiata, or Conchifera. These animals have an unsegmented bilateral body, with most of the organs and parts paired, but not repeated longitudinally. Most of them develop a mantle, which incloses either a branchial or a pulmonary cavity. They are generally more or less covered and protected by a calcareous shell, which may be univalve, bivalve, or multivalve. Note: Formerly the Brachiopoda, Bryzoa, and Tunicata were united with the Lamellibranchiata in an artificial group called Acephala, which was also included under Mollusca.

Phylum Mollusca Tree of Life Phylum Mollusca Kingdom Animalia Phylum Mullusca is both large and diverse. Molluscs comprise the familiar animals commonly known for both their shells and fine seafood, including snails, clams, octopus and squid. Molluscs' development suggest a close ancestral relationship to other protostomes, notably the Annelids, that includes segmented worms. Mulluscs are believed to have appeared near the base of the Cambrian and have left an extensive fossil record of several tens of thousands of species. Science believes Molluscs fully participated in the Cambrian Explosion phenomena, with the appearance and disapperance of many forms, many of which remain undiscovered in the fossil record Gastropods, Bivalves, and Cephalopods, the major groups of interest as fossils, diversified and specialized into the Ordovician to become ubiquitous throughout marine ecosystems. They adapted with the new selective pressures as other marine life forms similrly expanded, and they became both hunter of and hunted by new forms. The fossil record attests to the bivalves adapting to fresh water environments in the

JOHN D. TAYLOR, ed. Oxford University Press, Oxford, 1996. xiv + 392 pp., illustr., index, $135.00 (ISBN 0-19-854980-6 cloth). In September 1993 the Malacological Society of London celebrated its centennial by hosting a Centenary Symposium entitled "Origin and evolutionary radiation of the Mollusca." The 31 chapters of this volume were presented as part of that symposium and represent the revolution of thought and technique being applied to studies of molluscan evolution. In general, the book is marked by clarity of explanation, discussion of potential sources of error, and guidelines for future research. Although probably no two authors are in agreement on the major features of molluscan evolution or how those features can best be elucidated, there is a general feeling of collaboration and exploration in these chapters. The book is also a milestone in the increased application of phylogenetic systematics to assess molluscan relationships.

Mollusks Next to the arthropods, Mollusca is he largest phylum of invertebrate animals. It contains many familiar forms. The word "mollusk" means soft, and members are characteristically soft bodied. The only hard part of these animals is the protective shell, and even this is absent in some groups. Mollusks may be more active and conspicuous during the warmer season when they spawn. Some mollusks are active during the day but many are nocturnal. The mantle of the animal is responsible for depositing the layers of calcium carbonate and slowly expanding the shell into many diverse forms. Factors affecting the shell growth rate include available food, temperature and spawning. (Gastropod Album) The term Gastropoda means "stomach foot" and refers to the soft parts of these animals. Snails can pull back into their shells when disturbed. Some even have a door, or operculum, which closes the aperture when the animal retreats inside the shell. The opercula, which resemble round buttons or "cat's eyes" are often washed up on beaches. Many empty gastropod shells are inhabited by hermit crabs after the snail has died or been removed, although hermit crabs themselves do not kill gastropods to acquire the shell. (Ophistobranch Album) (See Nudibranch Section) The members of this order have no shell or mantle cavity and their body shape is elongated and symmetrical. The gills are exposed, thus the name "nudi" (naked), "branchia" (gills). Usually encircle the anus on the upper side. Individuals of this group are among the most brightly colored and attractive animals on the reef. Nudibranchs usually remain under coral heads where waves or currents will not disturb them. Most nudibranchs are carnivores, feeding on coral polyps and other shell animals. some coral polyp eating nudibranchs are able to incorporate live, stinging nematocyst cells (derived from the cnidarians) into their own skins, using these for their own protection.

All have soft bodies and have a strong muscular foot, which is used for movement or grasping. They also have gills, a mouth and an anus. A feature unique to molluscs is a file-like, rasping tool called a radula. This structure allows them to scrape algae and other food off rocks and even to drill through the shell of prey or catch fish. The diversity of molluscs impressively demonstrates how a basic body plan can evolve into a variety of different forms adapted to specific environments. For example, the hard shell in a land-dwelling snail is relatively large and serves to protect the animal. In the fast-swimming squid, however, the shell is reduced to a small internal pen-shaped structure.
