Species of octopus and squid live throughout the ocean depths and some species of clam and limpet live in the abyssal depths of the oceans around hot vents.

Lophotrochozoa The Mollusca Sea slugs, squid, snails, and scallops An introduction A cuttlefish, a coleoid cephalopod, moves primarily by undulating its body fins. Mollusca is one of the most diverse groups of animals on the planet, with at least 50,000 living species (and more likely around 200,000). It includes such familiar organisms as snails, octopuses, squid, clams, scallops, oysters, and chitons. Mollusca also includes some lesser known groups like the monoplacophorans , a group once thought to be extinct for millions of years until one was found in 1952 in the deep ocean off the coast of Costa Rica. Molluscs are a clade of organisms that all have soft bodies which typically have a "head" and a "foot" region. Often their bodies are covered by a hard exoskeleton, as in the shells of snails and clams or the plates of chitons. A part of almost every ecosystem in the world, molluscs are extremely important members of many ecological communities. They range in distribution from terrestrial mountain tops to the hot vents and cold seeps of the deep sea, and range in size from 20-meter-long giant squid to microscopic aplacophorans , a millimeter or less in length, that live between sand grains.

Home Page Site Map ... Me Taxonomy of the Phylum Mollusca by Winston Barney, June, 2000 How Scientists Classify Mollusks Classification is the arrangement of organisms into groups with regard to their natural relationships (systematics) and according to established criteria (taxonomy). The terms classification, systematics, and taxonomy are often used interchangeably because they apply to the same concept of arranging things in their "correct" relationship. We classify things as soon as begin to think... as toddlers we soon learn the different colors and shapes. We develop tastes for "good" food and "bad" food, and learn the difference between parents, friends, and "strangers". In our adult lives we classify many items in our daily routines: department stores are, by definition, divided into different departments. Grocery stores have separate sections for different kinds of items. Auto dealers, electronic stores, fast food chains are all categorized. Most children can sort a pile of seashells into fairly correct relationships simply by comparing shapes. But we know that the relationships between living things go much deeper than shape or size, so let us examine the ways that scientists classify the subject of this site - the molluscs!

The Phylum Mollusca (an Introduction, for High-school level students, and all others interested!) By Avril Bourquin Some Science Editing by Ross Mayhew May, 2000 Note: Glossary and separate page links are in blue and underlined. You may have to use your back button to navigate back to article when in the glossary or in external web sites or pages. Early Beginnings: The time is now about 600 million years ago and the first molluscs have made their appearance on our world. About 100 million years later, during the Ordovician period, at least six of the seven classes of molluscs represented today were present. Many of these first molluscs were but simple, worm-like animals, having segments similar to what we find in annelid worms and arthropods. These first molluscs crawled about the primeval seas, probing for and eating microscopic bits of food. The great landmass of Pangaea slowly deposits dissolved salts and other chemicals into the ocean. The first primitive molluscs in these oceans now digest these chemicals and begin to use the nutrients to build themselves protective shelters (shells) against their hostile environment. As Pangaea breaks apart around 200 million years ago, the world's great continents slowly migrate, due to plate tectonics, and we begin to recognize the world continents as they are today. Over time, the molluscs flourish and evolve to fit newly developing habitats. Fossil records show some groups ("taxa") growing larger, some smaller. Some grow spiny, others, shiny. Some coil tighter, some looser. Some coil left to right while others loose their coil all together. Some even loose their shells completely. Some, like the ammonids, evolve into huge numbers of species, and then mysteriously disappear forever only to be found as fossils. About 400 Million years ago, some of these molluscs, first the

The Phylum Mollusca Etymology:- From the Latin Molluscus meaning soft of body. Characteristics of Mollusca:- 1)Bilaterally symmetrical. 2)Body has more than two cell layers, tissues and organs. 3)Body without cavity. 4)Body possesses a through gut with mouth and anus. 5)Body monomeric and highly variable in form, may possess a dorsal or lateral shells of protein and calcareous spicules. 6)Has a nervous system with a circum-oesophagal ring, ganglia and paired nerve chords. 7)Has an open circulatory system with a heart and an aorta. 8)Has gaseous exchange organs called ctenidial gills. 9)Has a pair of kidneys. 10)Reproduction normally sexual and gonochoristic. 11)Feed a wide range of material. 12)Live in most environments. Introduction After the Arthropods the Molluscs are the most successful of the animal phyla in terms of numbers of species. There are about 110,000 species known to science most of which are marine. They occupy a vast range of habitats however both aquatic and terrestrial, from the arctic seas to small tropical streams and from valleys to mountainsides 7,000 metres high, there are a few adapted to live in deserts and some are parasitic. They also exhibit an enormous range in size, from species which are almost microscopic to the largest of all invertebrates the giant squid which can weighs 270 kg and measures up to 12 metres long in the body, with tentacles as much as another 50 metres in length. Many species are common and many more a beautiful. Most species secrete a shell of some sort, these shells are long lasting and have been collected by human beings for thousands of years, some of these shells, and the pearls which come from oysters, which are also molluscs may be among the earliest forms of money.

Burch, Ph.D. Kingdom: Animalia Phylum: Mollusca Class: Gastropoda Members of this Class The Class Gastropoda includes the snails and slugs. Most gastropods have a single, usually spirally coiled shell into which the body can be withdrawn, but the shell is lost or reduced some important groups. Gastropods are characterized by "torsion," a process that results in the rotation of the visceral mass and mantle on the foot. The result is that the mantle cavity (including anus) lies in the anterior body, over the head and mouth, and the gut and nervous system are twisted. Torsion takes place during the veliger stage, usually very rapidly. Veligers are at first bilaterally symmetric, but torsion destroys this pattern and results in an asymmetric adult. Some species reverse torsion ("detorsion"), but evidence of having passed through a twisted phase can be seen in the anatomy of these forms. Many snails have an operculum, a horny plate that seals the opening when the snail's body is drawn into the shell. Gastropods have a muscular foot which is used for "creeping" locomotion in most species. In some, it is modified for swimming or burrowing. Most gastropods have a well-developed head that includes eyes, 1-2 pairs of tentacles, and a concentration of nervous tissue (ganglion).

Phylum Mollusca: Mollusks After reviewing this section, the student should be able to determine the identifying physiological characteristics of Mollusks, identify body supply systems, and discuss the major classes of Mollusks: class Bivalvia, class Gastropoda, and class Cephalopoda. The mollusks constitute one of the largest phyla of animals, both in numbers of living species (at least 47,000, and perhaps many more) and in numbers of individuals. A significant characteristic of mollusks is their possession of a coelom , a fluid-filled cavity that develops within the mesoderm. The coelom not only functions as a hydrostatic skeleton but also provides space within which the internal organs can be suspended by the mesenteries. All mollusks have a soft body (their name is derived from the Latin word mollus , meaning "soft"), which is generally protected by a hard, calcium- containing shell. In some forms however, the shell has been lost in the course of evolution, as in slugs and octopuses, or greatly reduced in size and internalized, as in squids. Structurally, mollusks are quite distinct from all other animals. However, all modern mollusks have the same fundamental body plan. There are three distinct body zones: a
