Why do goldfish have teeth?

Goldfish, like other members of the carp family, don't have teeth in the traditional sense. Instead, they have pharyngeal teeth, which are located in their throat.

Here's how it works:

* Pharyngeal teeth are small, bony structures that are located in the back of the mouth, on the pharyngeal bones.

* These teeth aren't visible, and they aren't used for biting or chewing like traditional teeth.

* Instead, they work like a grinding mill to crush and grind food. When the goldfish swallows food, the pharyngeal teeth move against each other to break down the food into smaller pieces that can be easily digested.

So, while goldfish don't have teeth in the front of their mouth, they do have teeth in the back of their throat that help them eat and digest their food.
