Topic: Mollusca



  
 Mollusca Information Center
We at the MIC are aware that there are growing controversies about the nature of mollusca - what organism is responsible, whether or not it can truly be called a "disease," how many people are infected, and what, if anything, should be done about it.
Good News From Medicine -- A brief note about how mollusca is being researched in the laboratory as a way of helping infertile couples.
Lidak Pharmaceuticals [link broken] -- They're testing their anti-viral medication n-docosanol against the clam, working on the theory that the virus Selo Thoxxyn-P Five, found associated with mollusca lesions, is the organism responsible for mollusca.

 Parasitic Mollusca by Felix Lorenz
Modern parasitology can be divided in three mainstream disciplines, each of which have their starting point from the hosts involved: the first has a medical approach as it dwells upon those types of parasitism causing disease in humans.
First, to overcome the problem of immobility and the consequenting danger of populations being swept out of rivers (freshwater mussels).
While there is a wide range of literature dealing with the life-strategies of these groups, no monographic work has ever been published on the Mollusca as a phylum bearing a wide range of parasitic species and an even wider range of strategies.

One of the distinctive characteristics of the phylum is the soft internal body which is contrasted by the generally hard-shelled exterior (Hickman, 1961).
Also well developed in the Mollusca are the digestive, circulatory, respiratory, excretory, nervous, and sensory systems.
Below this lies the body, which is encased in the mantle cavity (Clarkson, 1993).

 Wildlife of Sydney - Overview of molluscs - Mollusca
Despite the many differences in external appearance, their internal structure is very similar.
Mollusca means 'soft-bodied' and, although some have developed a tough shell, they are all soft on the inside.
Molluscs are further classified into seven major groups and Sydney has representative from five of these.

These range from tiny snails, clams, and abalone to the octopus, cuttlefish and squid (which are considered the most intelligent invertebrates).
Many have a feeding structure, the radula, mostly composed of chitin.
Radulae are diverse within the Mollusca, ranging from structures used to scrape algae off rocks, to the harpoon-like structures of cone snails.

 Mollusca do not die on land - Deccan Herald
Mollusca’s adaptation mechanisms were investigated by researchers of the Severtsov Institute of Ecology and Evolution Problems, Russian Academy of Sciences.
The respiration problem is also solved by water mollusca in different ways.
However, it will soon be nothing to breathe in the ‘house’, and then chemical changes take place in the mollusc’s organism, these changes allowing it to live without oxygen or interaction with the environment.

The phylum also provides some of the most familiar animals, such as snails, clams, mussels, squids, and octopus (which, like the arthropods, are well known because they're good to eat).
The phylum Mollusca also includes lesser known forms such as the chitons, tusk shells, solenogasters, among others.
The molluscs rival the arthropods in their diversity of body forms and sizes, as well as their ecological success.

 Mollusca
The organisms in the phylum Mollusca are characterized by having three main body areas: a head-foot (sensory and locomotion structures), a visceral mass (excretory, digestive, and circulatory structures), and a mantle (which secretes the shell).
The gills, which function in respiration, are located between the visceral mass and the mantle.
In some forms, the soft bodies are protected by a calcareous shell.
