Phylum Mollusca Domain Eukarya Kingdom Animalia Phylum Mollusca Pictures Courtesy of The University of Arizona Tree of Life The Phylum Mollusca is made up of over 150,000 diverse species appearing very different but sharing certain basic characteristics. All mollusks have a muscular foot used for locomotion, as well as a mantle, an outgrowth that covers the animal. Many mollusks have an external calcium carbonate shell, hanging over the mantle, that is actually produced by the mantle. The mantle is also used in respiration, waste disposal, and sensory reception. It often creates a mantle cavity, where the gill is housed. The gill of a mollusk extracts oxygen from the water and disposes of waste. All species of the phylum Mollusca have a complete digestive tract, spanning from the mouth to the anus. Many also have a radula, a unique organ composed mostly of chitin, in the mouth. The radula allows the animal to scrape food from surfaces, especially the ocean floor, by sliding back and forth. Mollusks have a coelom, which is develops from solid cell masses. This makes all species in this phylum protosomes. All organs are suspended in mesentary tissue within this mesodermic coelom, between the outer covering (ectoderm) and the digestive tube (endoderm) of the animal. Interestingly, the phylum Mollusca is one of only two major coelomate phyla that do not have body segmentation (the other being Echinodermata, as well as other lophophorate phyla). There are seven main classes of mollusks.

Cnidaria Platyhelminthes Aschelminthes Annelida ... Chordata Introdução Os moluscos invadiram quase todos os ambientes; costuma-se dizer que só não há moluscos voando. Ocorrem das fossas abissais até as mais altas montanhas; das geleiras da Antártica até desertos tórridos. Vários grupos de bivalves e gastrópodes saíram do mar e invadiram a água doce e, no caso dos gastrópodes, o ambiente terrestre. Existem moluscos predadores (até mesmo de vertebrados), herbívoros, ecto e endoparasitas, filtradores, comensais, sésseis, vágeis, pelágicos, neustônicos etc. Em certos ambientes representam grande biomassa e podem ser importantes na reciclagem de nutrientes. Em que pese toda a supracitada gama de interesse humano, dentre outras não mencionadas, a quantidade de pessoas que já se dedicaram ao estudo desses animais é proporcionalmente pequena, e muito conhecimento necessita ainda ser gerado para que este atinja um nível satisfatório. Morfologia Os moluscos são animais triblásticos, celomados e protostômios. Apresentam o corpo mole, não segmentado, e com simetria bilateral. A cabeça ocupa posição anterior, onde abre-se a boca, entrada do tubo digestivo. Muitas estruturas sensoriais também localizam-se na cabeça, como os olhos. Sensores químicos também estão presentes nos moluscos e permitem pressentir a aproximação de inimigos naturais, quando o molusco rapidamente fecha sua concha, colocando-se protegido.

Mollusks are soft-bodied, and most have a prominent shell. The members of this highly successful and diverse phylum are mostly aquatic and include the familiar scallop clam oyster mussel ... chiton , and a variety of others. Mollusks occupy habitats ranging from the deep ocean to shallow waters to moist terrestrial niches. Certain mollusks, such as clams, squids, and scallops, constitute important food staples, and molluskan shells are highly valued by collectors. In times past these shells were used as money and today are used ornamentally for such items as buttons and jewelry. There are six classes of mollusks.

CONCHOLOGY 101 What is a Mollusk? Molluscan classes Naming Names Establishing Relationships ... Species Classification of the Mollusca Gastropoda Bivalvia Scaphopoda Cephalopoda ... Polyplacophora A Classification of the Mollusca by Dr. Gary Rosenberg The following classification ( ) reflects many changes in ideas of molluscan relationships in the last fifteen years, particularly among gastropods. The subclass Prosobranchia, which is normally considered to include all the gastropods except the pulmonates and opisthobranchs, is not recognized. Biological groups should include the common ancestor and all of its descendants, but when defined in this way, Prosobranchia becomes a synonym of Gastropoda. Thus, an increasing number of biologists, prefer to use prosobranch as a descriptive term, rather than as the name of a taxon. The Archaeogastropoda suffer from the same problem. Some workers restrict the archaeogastropods to the Pleurotomarioidea, Fissurelloidea, and Trochoidea, excluding the Cocculiniformia, and Patellogastropoda, others prefer the name Vetigastropoda for this group, to avoid confusion between a narrowly and a broadly defined Archaeogastropoda. As shown in an evolutionary tree , there are many different major lineages of gastropods. If this tree is correct, it would be appropriate to consider each of these lineages a subclass. In the classification herein, they are ranked as orders, because no name of subclass rank has been introduced for some of them. In order to maintain consistency of ranks within the tree, Pulmonata and Opisthobranchia are called orders, although they are usually considered subclasses. The problem of non-equivalence of ranks results from various groups of workers with disparate traditions working on different groups of gastropods. At present it is impossible to present a classification that simultaneously gives consistent ranks and reflects current usage; this classification represents a compromise between the two.

This site is dedicated to to research and management of the the exotic New Zealand mudsnail, Potamopyrgus antipodarum Dave Richards Billie Kerans and Dan Gustafson as well as many other cooperators . This site is hosted from the Department of Ecology at Montana State University-Bozeman . Additions and corrections are welcome from anyone. New home page Introduction The New Zealand mudsnail, Potamopyrgus antipodarum (Gray) was first discovered in the mid-Snake River, Idaho in the 1980's. It is now rapidly spreading throughout the western USA and has become established in rivers in seven western states and three national parks. It is a parthenogenic livebearer with high reproductive potential. The New Zealand mudsnail often reaches densities greater than 100,000/m2 in suitable habitat and has been reported to approach densities as high as 750,000/m2 in sections of rivers in Yellowstone National Park. Frequently, these mudsnails will comprise over 95% of the invertebrate biomass in a river. To date, limited research has documented decreases in native macroinvertebrate populations in several rivers where the mudsnail has invaded. Potamopyrgus antipodarum has also been shown to drastically alter primary production in some streams. Its invasion has generated much concern about the potential impacts it may have on native species, fisheries, and aquatic ecosystems in the western USA. Its spread into new systems is considered to be primarily human caused.

Molluscs are one of the largest animal phylums, with between 50000-110000 species! Octopus, squid, snails, nudibranchs, and bivalves are all molluscs. There is much diversity in this group, but most members have a shell made of calcium carbonate set in a protein matrix. The shell is made of three layers: the outer, organic periostracum, the middle, calcareous prismatic layer, and the calcareous inner nacreous layer. The shell is secreted by a tissue called the mantle. Most molluscs also have a muscular "foot" that is used for locomotion. The "inside scoop" on a typical gastropod. Snails and nudibranchs belong to the Class Gastropoda. Gastropods are diverse in terms of habitat and biology. Because they are often slow moving, many have well-adapted chemical and behavioural responses to predators. The columellar muscle retracts the soft body into the shell, and a hard proteinaceaous disc called the operculum functions as a trap door. The Class Bivalvia includes clams, mussels, oysters and scallops. Bivalves have a hinged shell with two valves and a spacious interior (mantle) cavity. They are usually sedentary and filter or deposit feed. Siphons are used for the inflow and outflow of water, and these can be extended for some distance, so that the bivalve can hide underground away from predators.

Chiton Food Chain BIVALVES Clam Life Cycle - Received from Kenny in New York. Q: Could you describe the life cycle of a clam from fertilization to adult stage? How does a clam's nervous system help it respond to changes in its environment? A: Some clams in the family Veneridae have built in biological clocks. If you were to put a clam in an aquarium, in a darkened room far from the ocean, it would still open during times of high tide on its home beach, and close during times of low tide. It is likely that this biological clock is controlled by its nervous system. One way that this clock could help the clam out is by preparing the digestive system an hour or so before the rising tide covers the animal. This way, the clam is ready to filter the water and eat the moment the tide covers it, and does not have to wait for environmental cues.

References The Molluscs are a large and diverse group of soft-bodied unsegmented animals. Nearly 130,000 recent species are known, and some 35,000 fossil species. They include many familiar animals, like snails, clams, squid, octopii, etc, as well as otehrs not so well known. They range in size from microscopic forms to the giant squid (Architeuthis), and have a long and venerable history appearing during earliest Cambrian time, if not before. Physiology All Molluscs possess some or all of the following characteristics: a muscular fleshy foot which with gastropods (snails) is used to crawl along with but in cephalopods is modified into tentacles a visceral mass containing the digstive, excretory, and reproductive organs a mantle , usually two folds that enclose the gills or lungs, and also secretes the protective shell a radula , a tongue-like feeding organ, essentially a sort of built-in saw equipped with rows of microscopic teeth that is incredibly effective at scraping food off hard surfaces or grinding through any substance (some carnivirous snails are able to bore a whole through the shells of other molluscs) a special respiratory gill (the ctenidium a shell made of calcium carbonate. This fossilises easily, which explains the rich fossils record the molluscs possess.
