Question

Why caterpillars need to shed their skin when they grow bigger

Answer 1

Caterpillars are the larval forms of butterfly. Caterpillars shed their skin 3-5 times while they grow and this process is known as molting. Their skin never grows as like human skin grows, so while growing they had to crawl out their skin when their skin becomes too tight. After first molting they brings new skin covers and in the mean time some caterpillars also eat their shed old skin. After they grow more, they again shed their skin.
