The exoskeleton of arthropoda - or the cuticle with which they are covered - is made largely of a tough protein called chitin, a long chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals where it would be found in hair, nails, hooves, claws, beaks, etc.
Some arthropods, like crustaceans, further harden their chitin exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed it (moult) in order to grow.

The external covering on arthropods is called the exoskeleton (or cuticle). It is made of a tough protein called chitin, a long chain polymer comparable to cellulose. Because it's inflexible, arthropods need to shed it (moult) in order to grow.
Do arthropods have backbones?No, it is the exoskeleton that holds the arthropod's body together. arthropods are invertebrates, which means they do not have backbones.

Crayfish are crustaceans, and therefore have a shell-like outer covering called an exoskeleton.

Ants don't have bones. Like other insects, they are arthropods and have an exoskeleton (hard covering outside their body) instead.
A cuticle is part of the human fingernail. Cuticle can be used to refer to the organic hard outer covering of any organism, including arthropods (of which cricket is a member).
Arthropoda (the arthropods) is a taxon or classification referred to as a phylum. Arthropods are characterized by the presence of an exoskeleton made from chitin, joint appendages, and a segmented body.
