The arthropod exoskeleton allows for a fully developed coelom.

  

Having a rigid surface for muscle insertion makes muscle contraction slow and inefficient.

  

The exoskeleton itself consists of layers of tough proteins interwoven by a stiff molecule called chitin.

  

The presence of both an exoskeleton and a hydrostatic skeleton makes the architecture of arthropods unique.
