<p>The characteristics of Mollusca imply that regardless of its diversity and class the mollusks are a very successful group. In terms of the living species on earth they have almost 100,000 different varieties that we can find in the marine and inlands.  The characteristics of Mollusca are still maintained even they are so complex and diverse and each classes have their own different looks and appearances wherever they live. Wherever the mollusks are dwelling be it in the deepest ocean trenches to the terrestrial domain they can survive and adapt to the new environment. <br />
<P><?php echo $fon_product_ad; ?></P>The best features and characteristics of Mollusca that made these creatures unique is that their ventral bodies are bilaterally symmetrical, none segmented and with a definite head and as a muscular foot. Their muscular feet are used for locomotion. At the back of the body the wall forms the mantle and a mantle cavity that is the breeding ground of shell formation. The Calcium Carbonate compound id excreted and sometimes there may be some molluscans that have shells and some that don’t. Surface epithelium usually ciliated, bearing mucous glands and sensory nerve endings. Even these creatures have complex systems the characteristics of Mollusca is common. Most of them have heart, lungs, digestive organs, grasping organ, gills, sensory organs used for touching, tasting and smelling. Most of the mollusks inhabit the waters as well as the land and since they are evolution, they have become adapted to living in nearly all available habitats.<br />
<br />
The characteristics of Mollusca phylum for all the 8 classes of that comprise an extreme diverse body forms on the outside (snails, oysters, chitons, clams, octopus, slugs, squid, among others) are remarkable and uniform basic plan of structure and function. The phylum name is derived from mollis, meaning soft, referring to the soft body within a hard calcareous shell, which is usually diagnostic. Soft-bodied mollusks make extensive use of ciliary and mucous mechanisms in feeding, locomotion, and reproduction. Most molluscan species are readily recognizable as such.<br />
<br />
Learning about the key features and characteristics of Mollusca can be found in science books and online science encyclopedias to give people a better understanding about the life of these beautiful creatures in the land and waters. These are one of the unique creatures that are so diverse and complex but their life is easy to understand. They can live in the marine, inlands, and in the soft and dumpy soils. They are highly adaptable when migrating to another environment. Despite of their differences in class and variation in size and shape one thing is for sure the characteristics of Mollusca is the so alike.</p>
