Which group of organisms do slugs and snails belong to?

Slugs and snails belong to the group known as mollusks. This classification is based on their biological characteristics and anatomy. Mollusks are a diverse group of invertebrates characterized by their soft bodies, which often have a hard shell for protection (although slugs have a reduced or absent shell). They possess a muscular foot used for movement, a mantle that covers their body, and a radula, which they use for feeding. This group includes not only slugs and snails but also other creatures such as clams and octopuses.

Understanding this classification is crucial, as it highlights the unique evolutionary adaptations and ecological roles mollusks play in various environments. For instance, slugs and snails can be important decomposers in ecosystems, breaking down organic matter and recycling nutrients. Recognizing them as mollusks distinguishes them from other groups like arthropods, which include insects and crustaceans, and fungi, which are completely different organisms. This classification aids in the study of their behavior, habitats, and interactions within the ecosystem.
