What is the Difference Between Cuticle and Exoskeleton? What Does an Arthropod Have?
Cuticle
The cuticle is a thin, non-cellular layer that covers the outer surface of an arthropod's body. It is composed of chitin, a tough, fibrous material that provides strength and protection. The cuticle is also waterproof, which helps to prevent desiccation.
Exoskeleton
The exoskeleton is a hard, external skeleton that covers the entire body of an arthropod. It is made of chitin and other materials, such as calcium carbonate. The exoskeleton provides support and protection for the arthropod's body. It also provides attachment points for muscles, which allow the arthropod to move.
Which Does an Arthropod Have?
All arthropods have a cuticle. However, only some arthropods have an exoskeleton. The exoskeleton is found in insects, crustaceans, and arachnids. Myriapods (centipedes and millipedes) have a cuticle but no exoskeleton.
