Detailed explanation-1: -In shelled molluscs, the mantle is the organ that forms the shell, and adds to the shell to increase its size and strength as the animal grows. Shell material is secreted by the ectodermic (epithelial) cells of the mantle tissue.

Detailed explanation-2: -A mantle, a highly modified epidermis that covers and protects the soft body. In most species, the mantle also secretes a shell of calcium carbonate.

Detailed explanation-3: -Molluscan shellfish typically have a hard shell, made up of calcium carbonate, as aragonite or calcite, deposited within an organic matrix. The shell is secreted by the mantle or epidermis, which underlies it and surrounds the body.

Detailed explanation-4: -Nacre or mother of pearl is secreted by mantle’s.

Detailed explanation-5: -The mantle is a layer of tissue that lies between the shell and the body. It secretes calcium carbonate to form the shell. It forms a cavity, called the mantle cavity, between the mantle and the body. The mantle cavity pumps water for filter feeding.
