Mollusks Clams, Mussels and Oysters are common types of Mollusks. Mollusks are invertebrates that live in ocean, freshwater and terrestrial habitats. It is estimated that there are as many as 120,000 different species of mollusk.There are several different classes of mollusk.The most common mollusks are the gastropods (e.g., snails and slugs), the cephalopod (e.g., octopus, squid and cuttlefish) and the bivalve (e.g., clam, muscle, oyster and scallop).The Giant Squid and the Colossal Squid are the largest animals without a backbone.he most common mollusks are the gastropods (e.g., snails and slugs), the cephalopod (e.g., octopus, squid and cuttlefish) and the bivalve (e.g., clam, muscle, oyster and scallop).

What are the types of mollusks? There are 5 main classes of mollusks, and two smaller classes that most people have never heard of. The principle classes are: Gastropoda (gastropods) - snails, slugs, conchs, whelks, cowries, etc. Bivalvia (bivalves) - clams, mussels, oysters, cockles, scallops, etc. just now. Report Abuse. The living mollusks are placed into seven classes (some workers combine the Solenogastres and Caudofoveata into a single class called Aplacophora): Solenogastres Caudofaveata Polyplacophora Scaphopoda Cephalopoda Bivalvia Gastropoda There are over 50,000 different types of mollusks alive today.

- Mollusks. The phylum Mollusca is the largest and most diverse phylum of animals next to arthropods. Mollusks can be found in nearly every ecosystem on earth, from high, barren mountains to grassy plains, lakes, rivers and in all seas and oceans.

- Slugs and snails belong to the class Gastropoda of molluscs (soft-bodied animals). Most gastropods are aquatic, but one group (subclass Pulmonata) have expanded into terrestrial habitats. Terrestrial snails and slugs in New Zealand are extremely diverse, and come in a variety of colours, shapes and sizes.

List of the Three Major Body Regions of a Mollusk The visceral mass includes all of the mollusk's organs. These organs include a three-chambered heart in most mollusks and three separate hearts in cephalopods. Unlike most mollusks, cephalopods have closed circulation system. All mollusks have highly developed tubes that perform their kidney functions.

- The Phylum Mollusca All mollusks are classified under the phylum Mollusca. There are six classes of mollusks: 1. Class Cephalopoda This class includes the highly intellegent, many-armed orders of mollusks.

Land, Ocean, or Freshwater: Learning About Gastropods Gastropods make up the family of animals that include snails, slugs, limpets and sea hares. These animals can be found in fresh or salt water as well as on land. They are the largest group of mollusks and have existed since the early Cambrian period. A single shell and an asymmetrical body characterize these animals.

Pearl-Producing Mollusks (Molluscs) Pearls of the Week. Pearl-Producing Mollusks (Molluscs) Pearl-Producing Mollusks (Pearl-Producing Oysters) Mollusks represent one of the world's earliest forms of animal life, and date back over 550 million years. Actual pearl-producing mollusks first appeared 530 million years ago, when mollusks developed shells.

- List the special adaptations which make this phylum successful on earth. Despite their very different appearances such familiar invertebrates as chitons, clams, snails, and octopuses are all mollusks, members of the phylum mollusca.he largest and most diverse class of mollusks is Gastropoda, which includes about 75,000 species of snails, slugs, abalones, nudibranchs, and conches. The name gastropoda means stomach-foot. Most gastropods have a single shell, or valve, and so are called univalves.

Characteristics of Mollusks Most of the mollusks live in water but some live on land. There are more than 110,000 species that have been identified. A theoretical, idealized mollusk would crawl on a single flat, muscular foot, and the body would have at least a suggestion of a head at one end and an anus at the other.

- There are over 50,000 known species of Mollusks, which makes them second only to the Arthropods in invertebrate phylum size. Among the Mollusks are some of the most well known of invertebrate sea creatures, like snails, clams, mussels, squid, and octopods.ollusks usually have a shell (although some do not). Mollusks also have an extension of the body wall called the mantle. This portion of the animal's anatomy is responsible for secreting the shell. The mantle encloses the mantle cavity which contains the Ctenidia (gills), anus and excretory pores.

Are Mollusks Invertebrates? Mollusks are a phylum of invertebrate animals defined by their distinct body structure -- a head, a visceral mass, a mantle and some kind of foot.ivalves. Clams, limpets, mussels, oysters and scallops are the most common types of bivalves, which also are mollusks. Bivalve means two shells, which is what these creatures have instead of a bone structure. Bivalves are filter feeders.

Land, Ocean, or Freshwater: Learning About Gastropods Gastropods are the largest family of mollusks and live almost everywhere. The life cycles of a gastropod can differ depending on where they live--land, ocean or freshwater. A specific example of each is detailed for better understanding of the variety.

Bivalve mollusks (e.g., clams, oysters, mussels, scallops) have an external covering that is a two-part hinged shell that contains a soft-bodied invertebrate.

In comparison with other invertebrates, mollusks are highly developed creatures.

- Mollusks produce pearls. It is theoretically possible for every species of bivalve to produce a pearl, although relatively few are known for pearl production. The most important pearl producing family in the class Bivalvia is Pteriidea, and specifically the genus Pinctada.

Among the Mollusks are some of the most well known of invertebrate sea creatures, like snails, clams, mussels, squid, and octopods. Although one might not see an obvious physical relationship between a snail and a squid, they are remarkably similar in construction.

A List of Mollusks The bivalve family of mollusks consists primarily of clams, scallops and other ocean creatures that have a hinged shell. That hinged shell is the hallmark of bivalves, and the shell is produced by the mollusk itself. As it grows, the mollusk secretes calcium carbonate, constantly rebuilding the shell.
