Exoskeleton Characteristics The exoskeleton of an arthropod is their tough, hard outer shell. It is made up mostly of chitin, which is a very strong material related to cellulose.

Bugs are designed to be small. They have an external skeleton as compared to animal's internal skeleton. This limits their size because an exoskeleton could not support a large organism.

Molluscs are a clade of organisms that all have soft bodies which typically have a "head" and a "foot" region. Often their bodies are covered by a hard exoskeleton, as in the shells of snails and clams or the plates of chitons.

Insects have exoskeletons (skeletons on the outside). Their skeletons are made out of thin, hard pieces or plates, like armour, made of chitin. All together, these pieces make a hard layer around the insect's body. The exoskeleton protects the insect.

Arthropod and vertebrate skeletons are quite distinct from each other. Basically, the vertebrate skeleton is internal (an endoskeleton) while the arthropod skeleton is external (an exoskeleton). ... The vertebrate skeleton is buried under skin and muscle.
