Students have asked these similar questions
Most land animals with exoskeletons are smaller than the volume of a mouse, and most vertebrates are larger than a mouse (marine invertebrates can be somewhat bigger). What keeps an insect with an exoskeleton from being as big as a horse?
What disadvantages associated with having exoskeletons did arthropods have to overcome to allow natural selection to favor this trait? How did they circumvent these problems?
Apart from structural support, what are other functions of exoskeleton in arthropods?
