Mollusca

Mollusca is a diverse group of soft-bodied animals that often have a hard shell for protection. This group includes creatures like snails, clams, octopuses, and squids. They typically have a muscular foot used for movement or digging, a visceral mass containing most of their organs, and a mantle that secretes their shell. Mollusks can live in aquatic or terrestrial environments and display a wide range of behaviors and adaptations. They play important roles in ecosystems, such as recycling nutrients and serving as food for other animals. Overall, Mollusca are an incredibly varied and fascinating group of animals.
