It is actually only three common structures since not all mollusks have shells. Here it is:
Head- structure that contains the mouth, brain and sensory organs
Foot- muscular structure that extends from the body and is used for movement
Mantle- fleshy tissue that covers and protects the internal organs. It also secretes the shell for most mollusks

bilateral symmetry
They are all soft-bodied.

It would seem so... mollusks have been found near deep sea vents as well as in high altitude mountain ponds (up to 10,000 feet above sea level).
They both live in the ocean and they have no bone structure.
Protoplast is found in all cells
Firt of all, it is spelt odontophore. A structure at the base of the mouth of most mollusks over which the radula is drawn back and forth in breaking up food.
No. Oysters are mollusks, which have shells rather than bones.
No. Squids and octopi are a class of mollusks called Cephalopods, and as with all mollusks, cephalopods are invertebrates.
ok first of all you mean how can mollusks be harmful and think of invasive species
The radula (or some form of the radula) is found in all classes of mollusks except bivalves (organisms with two shells such as clams).
