The external covering of an arthropod is referred to as an exoskeleton. In some arthropods (water varieties) the exoskeleton is composed mostly of calcium carbonate. In land varieties of arthropods, such as insects, their exoskeletons are made of a material know as chitin.

What is the arthropod skeleton composed of?

Arthropods have an external skeletal structure, or "exoskeleton", usually made from a material called "chitin", a natural-made carbohydrate-based polymer. Chitin is not unlike keratin (a protein-based natural polymer, used in other creatures to make nails, claws, hair, etc) in structure.

What are non-arthropods?

well i don't know about non arthropods but this is what i know about arthropods:- Arthropods have jointed legs and a head and segmented body parts called the thorax and abdomen. An arthropod's body is covered by a shell or a hard outer skin called an exoskeleton. It is made of a material called chitin. The exoskeleton has a special top layer, the cuticle, which is thick and tough. In crustaceans, the exoskeleton is sometimes called the carapace and hides the segmented body parts. by kira 7G
