It protects there internal organs.
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.
The mantle is the fold of tissue which protects the inside mass. If a shell is not present, then the mantle forms it.
The mantle of a clam protects the clam from sunlight in shelled mollusks, the mantle is the organ that forms the shell, and adds to the shell to increase its size and strength as the animal grows.
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 mantle retractor muscle is a muscle found in mollusks that is responsible for retracting the mantle. The mantle is a fold of skin that surrounds the internal organs of mollusks and plays a role in shell formation, respiration, and protection. The contraction of the mantle retractor muscle allows the mollusk to withdraw its soft body into the protective shell.
If ur doing the puzzle they're looking for whelk.
The thin layer of tissue that covers the body of a mollusk is called the "mantle."
The mantle excretes the calcium carbonate to make the shell of the animal... (Among other things...) By the way chap, lungs don't extract oxygen from water...
The membrane that surrounds the internal organs of mollusks is called the mantle. This tissue not only encloses the internal organs but also plays a crucial role in producing the mollusk's shell, if present. The mantle cavity, formed by the mantle, houses gills or lungs, facilitating respiration and excretion. Additionally, it is involved in the secretion of substances that help in shell formation and protection.
The mantle of the mollusk helps it protect its delecate skull and grows and shrinks when detectiong danger. The mantle also grows when sexually urged by female mollusks and the mollusk with the largest mantle wins over its mate.
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.
