Step 1

Arthropods have an exoskeleton of chitinous polysaccharide cuticle. It is periodically shed to allow for growth. It keeps the body size small, and gives structural strength to the body which is advantageous for colonization. Also, the hard exoskeleton protects them from water loss and predator attack. The periodical shedding of exoskeleton in Crustacea is also called as molting, which needs a molting hormone. the molting or shedding is often delayed by a peptide hormone names ad MIH or Molt-inhibiting hormone.
