I didn't mean about this section.

Techically - in legal terms - exotic are all the non-native animals that cannot survive in the considered country.
If they can survive, they´re considered "potentially invasive" or "invasive" if already introduced to the eco-system.

So, if this is the definition you seek, an "exotic pet" would be any pet from native of a different climate that would not be able to survive in your country/climate
