Verified step by step guidance1
Understand that mollusks are a diverse group of invertebrates that include snails, clams, and squids.
Recognize that the body structure of mollusks is typically divided into three main parts: the foot, the visceral mass, and the mantle.
The foot is a muscular structure used for movement and anchorage.
The visceral mass contains most of the internal organs, including the digestive, excretory, and reproductive systems.
The mantle is a significant part of the mollusk's anatomy that secretes the shell (if present) and covers the visceral mass.
