There is no one name for animals that do not have internal skeletons. Animals with an external skeleton are referred to as having an exoskeleton (adjective exoskeletal) and are commonly known as exoskeleton animals . There are many types of animals with exoskeletons, including crustaceans (crabs and lobsters) and insects such as grasshoppers and cockroaches. The shells of mollusks (snails, clams, etc) are also exoskeletons. In contrast to the internal skeleton, the external skeleton is not only designed to support but also protect the animal's body.

An invertebrate is an animal that does not have a spine. Some invertebrates have exoskeletons, such as insects and crustaceans. Others, such as worms, slugs and jellyfish, have neither an internal nor external skeleton.

Some animals, like the tortoise or turtle, have both an exoskeleton and an endoskeleton
