Nothing officially confirms all the animal species in the Kung Fu Panda franchise, so this is still one of many controversial questions. There are two main facts that contradict each other to create the controversy:
- Alligators are native to China, unlike crocodiles, and the most common (or at least well known) species of alligator in China is the Chinese alligator;
- There are some distinct differences between alligators and crocodiles, and most of the physical attributes of the "crocodiles" in the franchise seem to fit the crocodile criteria.
Because of this, the "crocodiles" in Kung Fu Panda are just left open to interpretation.
