Flys are insects and therefore invertebrates (they have no backbone to hold them together like we do!). As with many other invertebrates, flys are covered by an exoskeleton, like a shell.Cabs and lobsters are also invertebrates, their shells (exoskeletons) are very obvious when you have to crack them open to get to their muscles (yummy meat!) inside!
Exoskeletons are thought to have evolved as a way of holding an animal 'together' (to stop it flopping into a blob form, especially out of the water!)... Many exoskeletons can be found in the fossil record, giving us a picture of what some of the first animals to venture onto land may have looked like.
The exoskeleton has been a very successful, evolutionary strategy! Just look at the numbers on flies still buzzing around today, and they have armor to avoid being swotted too!
Exoskeleton of all insects are made up of chitin, which is a nitrogen containing polysaccharide. Chitin also makes up the cell wall of fungi.
