What is the name of a panda when it baby and its an adult?

There isn't a specific name for a baby panda that changes when it becomes an adult.

* Cub: This is the most common term used for a baby panda.

* Adult: This is the term used for a fully grown panda.

There's no special name transformation like you might see with some other animals (e.g., a baby deer is called a fawn).
