Animals that live in shells are commonly referred to as "mollusks." This diverse group includes organisms such as snails, clams, and octopuses, many of which possess a hard external shell for protection. Mollusks are characterized by their soft bodies and, in many cases, a muscular foot used for movement. Other shell-bearing animals, like certain crustaceans, may also be considered but are not classified as mollusks.

Annelids, mollusks, and arthropods are classified as invertebrates, which are animals lacking a backbone. They belong to the larger group called Coelomates, characterized by having a true coelom, a fluid-filled body cavity. Annelids are segmented worms, mollusks include diverse organisms like snails and octopuses, and arthropods encompass insects, arachnids, and crustaceans, all distinguished by their body structures and developmental processes.
No, not all animals have backbones. Animals are classified into two main categories: invertebrates (animals without backbones) and vertebrates (animals with backbones). Invertebrates make up the majority of animal species on Earth and include insects, mollusks, and jellyfish, among others.
