Molting is the process by which an arthropod sheds its exoskeleton to allow for growth. It involves the formation of a new, larger exoskeleton beneath the old one, which is then shed.
5 Must Know Facts For Your Next Test
Molting is controlled by hormones, primarily ecdysone.
During molting, arthropods are vulnerable to predators due to their soft, new exoskeleton.
The process includes several stages: pre-molt, molt, and post-molt.
Arthropods can increase significantly in size after each molting cycle.
Molting frequency decreases as the arthropod ages and reaches adulthood.
