What Is the Function of the Mantle in Mollusks?

There are numerous functions of the mantle in mollusks, with the primary function being to enclose and protect the internal organs. The mantle leaves room in the mollusks body for the mantle cavity, which holds air or water and serves as a method for respiration. Mantles in mollusks also provide a way for them to communicate with one another because of the bright colors.

The mantle on a mollusk is a tissue close to the outside of the body, which is where the sensory organs are located. Some species of freshwater mollusks have gills in the mantle cavity, which assist in respiration. The mantle cavity also provides a place for the mollusk's body to filter food particles out of water and also keeps eggs safe while they fully mature.
