The different "types" of ferrets that people refer to are actually all domestic varieties of the European polecat, selected for different traits like color, size, and temperament.
Here are some of the common "types" of ferrets:
* Standard Ferret: This is the most common type, with a variety of coat colors and patterns.
* Angora Ferret: Known for their long, fluffy fur.
* Albino Ferret: Ferrets with a white coat and pink eyes.
* Black-Footed Ferret: A separate species, *Mustela nigripes*, which is critically endangered and found only in the American West.
So, while there are many different appearances and names for domesticated ferrets, they all belong to the same species: the European polecat.
