Mollusks have soft body and hard shells but some don't even have shells.
a shell
hair covers the worms bodies
the cover of a mollusk is the mantel
the membrane is called the mantel
Mollusks have a mantle, which is a thin layer of tissue that covers their body and secretes the shell in shelled mollusks. The mantle plays a key role in respiration, excretion, and shell formation in mollusks.
Mollusks have a mantle, which is a protective layer of tissue that covers their soft body. The mantle plays a role in shell formation and can also secrete mucus for locomotion or defense.
The thin layer of tissue that covers the body of a mollusk is called the "mantle."
The operculus is a structure found in certain animals, particularly in mollusks and fish. In mollusks, it refers to a hard, protective lid that covers the opening of the shell, helping to seal the animal inside. In fish, the operculum is a bony flap that covers and protects the gills, facilitating respiration by allowing water to flow over the gills without the need for the fish to swim continuously.
All molluscs belong to the taxonomic domain of Eukarya.Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.
Cephalopods are a phylum of mollusks that include squids, octopi, the chambered nautilus, and cuttlefish. All cephalopods have tentacles, most are carnivores, and they are all mollusks. All mollusks have a radula, or toothy tongue, a mantle, or thin layer of tissue that covers the organs and makes the shell, and a muscular 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 -_-
