What is the name an animal and body parts it sheds off as grows?

The animal that sheds off body parts as it grows is called a crustacean.

Here's a breakdown:

* Crustaceans are a large group of arthropods that includes crabs, lobsters, shrimp, crayfish, barnacles, and pillbugs.

* Exoskeletons are the hard, outer coverings that protect crustaceans and other arthropods.

* Molting is the process by which crustaceans shed their exoskeletons as they grow.

Here's how it works:

1. As a crustacean grows, its exoskeleton becomes too small.

2. The animal secretes a new exoskeleton underneath the old one.

3. The old exoskeleton splits and the crustacean emerges.

4. The new exoskeleton is soft and flexible, allowing the animal to grow.

5. The new exoskeleton hardens over time.

So, while the animal itself doesn't have a specific name for the shedding process, molting is the term used to describe the shedding of the exoskeleton.
