The major use of the exoskeleton in arthropods are the following:
- protection
- barrier against dessication.
- excretion
- sensing
- support
- feeding
- defense from pests and predators
- attachment framework for musculature
To further explain, the exoskeleton has the following:
- epicuticle - acts against dessication, it is wax covered. This causes the trapping of water to avoid dessication.
- procuticle - provides the strength for the exoskeleton. It is a thick, inner, chitin–protein layer. The chitin functions for support and protection.
- exocuticle - The hardness of the exoskeleton in different arthropods is also sometimes related to the thickness and degree of tanning of the exocuticle.
Exoskeleton are made of or does contain chitin with the addition of calcium carbonate which really makes them harder and stronger.
