With or without the animal, there are left or right sides to the shell (and animal); apertural terminology differs, however. 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.
Most molluscs are marine. Molluscs' calcareous shell makes them very different from Mollusca & shells book animals, various as they may be. The assumption, the first molluscs of the early Cambrian period (about to Million years ago) had been creatures crawling on the ocean floor, explains the division of a mollusc's body into a soft ventral side crawling on the floor and a dorsal side exposed to the environment, which had to be.

MolluscS. Molluscs are a phylum of mostly marine invertebrates that includes octopus, mussels, clams, snails, chitons, squid and many more animals. They are characterized by a number of features that separate them from all other animals.
They have a muscular foot, a mantle which produces a shell and a visceral mass which contains all of their internal organs. In book: Freshwater Life.

Mollusks pull the soft portion of their bodies into their shells and seal the entry with their operculum. They can also burrow below the surface of the seafloor, river banks, river bottoms, or lake banks and lake bottoms.
Class Bivalvia consists of mollusks with two shells held together by a muscle; these include oysters, clams, and mussels. Members of class Gastropoda have an asymmetrical body plan and usually have a shell, which can be planospiral or conispiral.
Mollusc shells (especially those formed by marine species) are very durable and outlast the otherwise soft-bodied animals that produce them by a very long time (sometimes thousands of years even without being fossilized).
Most shells of marine molluscs fossilize rather easily, and fossil mollusc shells date all the way back to the Cambrian period. The term "conchology" is also used for the study of molluscs; however, it is usually applied to those that study the shell only.
Molluscs, in general, are soft-bodied animals that usually produce an external skeleton (called an "exoskeleton") we call a Shell, which is composed of a limey material: calcium carbonate (CaCO3) The shell serves both.

The mollusks are a diverse group (85, described species) of mostly marine species. They have a variety of forms, ranging from large predatory squid and octopus, some of which show a high degree of intelligence, to small grazing forms with elaborately sculpted and colored shells. Mollusks are soft-bodied invertebrates of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body.
Along with the insects and vertebrates, mollusks are one of the most diverse groups in the animal kingdom, with nearly(possibly as many as ,) described is a list of notable mollusks, ordered. Common and scientific names of aquatic invertebrates from the United States and Canada: Mollusks, 2nd ed.

This book has informations about Phylum- Mollusca which has great potential in aquatic resources. To value these shall animals their classification anatomy and physiological aspects of various class/genus are described with important biological systems like digestive, respiratory, circulatory, excretory, sense organs and reproductive etc.
The anatomy and physiology of animals pave the way for 2/5(1). Having thus cleared what might otherwise be muddy waters for some readers it is time to look more closely at the three main groups of edible mollusks.
Single Shells. The gastropods, or single shell mollusks, have contributed less to human nutrition than either the bivalves or the cephalods. This is not because the single shells are too small.

Molluscs (also called mollusks) are soft-bodied, unsegmented animals, with a body organized into a muscular foot, a head, a visceral mass containing most of the organ systems, and a fleshy mantle that secretes the calcareous shell.

Mollusca is the second-largest phylum of invertebrate animals after the members are known as molluscs or mollusks (/ ˈ m ɒ l ə s k /).Aro extant species of molluscs are recognized.
The number of fossil species is estimated betw andadditional species. The proportion of undescribed species is very m: Animalia. 44 Phylum Mollusca Molluscs. The phylum Mollusca is defined by several special characteristics. These defining characteristics include a mantle with a mantle cavity, a shell (except where lost), visceral mass, foot, and odontophore is in the mouth of most mollusks and it supports the radula (a ribbon of teeth).
In many molluscs, it moves forward while the radula contacts the food. Molluscs (phylum Mollusca) include clams, mussels, oysters, and snails, as well as numerous other families. With o recorded species in the world (estimates of total species exceeds ,), this phylum is second only to arthropods in number of living species in the world.
Mollusca is an incredibly diverse grouping of tiny (under 1 centimeter) and gargantuan (over 50 feet) species. Sea shells of the West Indies: a guide to the marine molluscs of the Caribbean.

Many mollusks have a hard external shell, but others do not. There are o different types of mollusks alive today. Some major classes of mollusks include the bivalves (like clams), cephalopods (like octopuses and squids), aplacophorans (worm-like mollusks), chitons, monoplacophorans, scaphopods (tusk shells), and gastropods (like.
Foot extends into substrate by relaxing of abductor muscles. Foot burrows and grabs on to substrate. Abductor muscles contract, drawing the shell valves close together. This forces water out and loosens some of the sediment. The pedal retractor muscles are contracted and the shell "rocks" back and forth as it cuts through the substrate.
Mollusks are a diverse set of creatures that have been around thousands of years.
