The arthropods all share membership in the phylum Arthropoda. Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.
The carapace in arthropods, along with the remainder of the exoskeleton, would be made mostly of a hard long-chain polymer protein called chitin. Crustaceans further harden this through biomineralization with calcium carbonate.
Sexually mostly, with a male and female. But many species can also reproduce asexually, as the females can lay unfertilized eggs which hatch into more females. Species that can do this include many stick insects and aphids. Also note that (sterile) female worker bees and ants hatch from unfertilised eggs, and male drones from fertilized ones.
