How come a fancy hamster is not on the list of all hamsters in world?

This question is a bit tricky! It plays on the idea of a "fancy hamster" being a specific breed. Here's why there's no list of "fancy hamsters" in the world:

* "Fancy Hamster" isn't a scientific term: The term "fancy hamster" is often used by pet owners to describe hamsters kept as pets, especially those with unusual coat colors or patterns. It's not a recognized scientific classification.

* Hamsters are classified by species: Scientists classify hamsters by their species (e.g., Syrian hamster, Dwarf hamster). There are different types within species, like the many color varieties of Syrian hamsters.

* No official registry: Unlike some animals like dogs and cats, hamsters aren't typically registered with breed organizations. This means there isn't a central database to track all the different varieties of hamsters.

So, in short, there's no list of "fancy hamsters" because:

* It's not a scientific term.

* Hamsters are classified by species, not by "fancy" traits.

* There is no central registry for hamsters.

It's fun to think of all the different types of hamsters out there!
