The mantle is an important part of the body of a mollusk. It forms the outer wall of the mollusk's body. The mantle encloses the mollusk's visceral mass, which is its internal organs, including the heart, stomach, intestines, and gonads. The mantle is muscular, and many species have modified it to use for siphoning water for feeding and propulsion.
