Here's why:
* Geographic Distribution: Giraffes are native to Africa, specifically sub-Saharan Africa. They are not found naturally in other continents like North America, Europe, Asia, or Australia.
* Introduced Species: When giraffes are found outside of their native range, it means they have been introduced either intentionally (e.g., for zoos or conservation efforts) or unintentionally (e.g., escaped from captivity).
* Definition of Exotic: The term "exotic" generally refers to species that are non-native to a specific location.
So, while a giraffe might be considered a common animal in Africa, it would be considered an exotic species anywhere else in the world.
