Why caterpillers need to shed their skin when theay grow bigger |
|
Answer» Answer: A caterpillar’s ‘skin’ is actually its exoskeleton, MADE of a hard MATERIAL called CHITIN. As the caterpillar grows, it’s exoskeleton does not grow with it. Instead it develops a new exoskeleton underneath, which is softer. A time COMES when the old exoskeleton can no longer stretch to ACCOMMODATE the caterpillar’s growth - this is when it sloughs off the old ‘skin’. |
