Question

The space between the mantle and foot in a mollusc is called the
A)hemocoel.
B)coelom.
C)enterocoel.
D)mantle cavity.
E)radular cavity.

Accepted Answer

The space between the mantle (a membrane that surrounds the body organs) and the foot (a muscular structure used for locomotion) in a mollusc is called the mantle cavity. The mantle cavity contains the gills and other respiratory structures in aquatic molluscs and is also involved in excretion and reproduction in some species. Hemocoel refers to the body cavity that contains the blood of some invertebrates, coelom is the body cavity found in many animals, and enterocoel refers to the primitive body cavity that forms during embryonic development in some animals. The radular cavity is a structure found in the mouth of some molluscs that is used for feeding and scraping food.
