proecdysis
zoology
Also known as: premolt
Quick Summary
In zoology, proecdysis is the preparatory stage before an animal sheds its outer body layer, a process known as ecdysis or molting. During pre-ecdysis, the old cuticle separates from the epidermis, and molting fluid is released to break down this layer. A new protective epicuticle forms to shield the epidermal cells. This process is crucial for growth and changes in body form in animals like arthropods, which have an exoskeleton. Ecdysis itself is the final act of shedding the old exoskeleton, allowing the animal to grow.1234
