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

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).
Mollusks without backbones are called invertebrates. Some examples of invertebrate mollusks include snails, clams, octopuses, and squid. These animals have soft bodies and are protected by a hard external shell or by their muscular structure.
Vertebral column is not present in all mollusks.
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.
Squids share two traits with other mollusks: a soft body typically covered by a mantle and a foot modified into tentacles. Additionally, both squids and other mollusks possess a radula, a feeding organ used for scraping food.
No. Oysters are mollusks, which have shells rather than bones.
ok first of all you mean how can mollusks be harmful and think of invasive species
