However, you could ask about the animal that eats the hottest peppers! That might be the ghost pepper (Bhut Jolokia), which is considered one of the hottest peppers in the world. While many animals can tolerate capsaicin (the compound that makes peppers spicy), some are known to enjoy it.
Here are some contenders for animals that can handle the heat:
* Birds: Many bird species, especially the roadrunner, are known to eat chili peppers. They don't have the same receptors for capsaicin as humans, so they can enjoy the flavor without the burning sensation.
* Raccoons: These clever critters are known to eat a variety of foods, including chili peppers. They can handle a bit of heat.
* Mice: Believe it or not, some mice enjoy eating chili peppers! While they might not eat the entire pepper, they seem to enjoy the flavor.
So, while there isn't a single "spiciest" animal, there are animals that can tolerate, and even enjoy, spicy foods!
