foot
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 :) B) =3 -_-
Some common features of squids and other mollusks include a soft body with a muscular foot, a mantle that secretes a shell (if present), and a radula for feeding. They also have a visceral mass containing organs such as the heart, digestive system, and reproductive organs. Additionally, mollusks possess a mantle cavity that houses the gills and functions in respiration. However, not all mollusks have all these features, as there is a wide diversity within the phylum.
Male have muscular body feature. Muscular , co'z weight lifter. Female ready for sex all the time/
muscles as in body muscles? or mussels as in sea mussels like mollusks?
Mollusks are soft-bodied animals often covered by hard shells. This group of invertebrates includes a variety of animals; snails, clams, and octopus are the most common. There are more than 85,000 species of mollusks and there is believed to be many more that haven't been identified.
Mollusks generally have a soft body enclosed in a protective shell made of calcium carbonate. The body consists of a muscular foot for movement, a visceral mass for digestion and reproduction, and a mantle that secretes and maintains the shell. Some mollusks, like snails, also have a radula for feeding.

A shell
All mollusks possess a soft body covered by a hard shell, a muscular foot for movement, and a mantle that secretes the shell. These characteristics distinguish mollusks from other phyla in the animal kingdom.
Mollusks have a soft, unsegmented body and live in aquatic or damp habitats, and most kinds have an external calcareous shell.
Muscular tubes in the body are often referred to as "muscular ducts" or "muscular tubes." An example includes the esophagus, which transports food from the mouth to the stomach through rhythmic contractions called peristalsis. Other examples include the trachea and various blood vessels, which also feature muscular layers to help facilitate the movement of substances.
Vertebral column is not present in all mollusks.
