What type of animals are mollusks?

Mollusks are classified as soft-bodied animals that are frequently characterized by the presence of a shell. This group includes a diverse range of species such as snails, clams, squids, and octopuses. The defining feature of mollusks is their soft anatomy, which contrasts with more rigid structures found in hard-bodied insects. The shell, when present, serves as protection and can be a vital part of their anatomy, contributing to their survival in various environments. Thus, identifying mollusks as soft-bodied animals, usually with a shell, captures the essential characteristics of this biological group, highlighting their unique anatomical and ecological adaptations.
