- Chitin
Chitin is a structural polysaccharide. Insects and bees, like the one in the picture, and crustaceans use chitin to build their exoskeleton. Also, chitin can be found in the cell walls of fungi and in some other places. ...

Exoskeleton: Anatomy and Physiology
In the far right corner is an ant. This little guy is as hard as rock, so if you were to step on him you would hear a crunch. This is due to his structure, ants have their skeleton on the outside, hence exo. This outer cover protects their body which an an evolutionary advantage because they are so small and vulnerable to danger. Having an exoskeleton means they are an invertebrate thereforethey don't have lungs and organs. Ants oxygen transports through their exoskeleton through spiracles.
