Why do animals have to malt?

Answer 1

Molting is a way in which the animal can shed off feathers, hair, horns, shell, or a layer of skin. In molting allows for new growth. Birds typically molt once a year, but some species molt up to three times a year. Mammals typically molt in the spring to get rid of the heavy coat. Deer they shed their antlers and grow another. Amaphibian (frog and toad) molts it skin every few weeks, expect in the winter. Lobster or other crustacean molt its exoskeleton in the spring/early summer.
