Yes, all fish have teeth, although their location, size, and shape vary greatly depending on the species and diet.
The Amazing Diversity of Fish Teeth
Fish teeth aren't just for biting; they play a crucial role in feeding and survival. Different fish have evolved different types of teeth adapted to their specific diets. Some fish, like goldfish, possess pharyngeal teeth located in the back of their throat, used for crushing food. Others, like sharks and pike, have prominent, sharp teeth for seizing and tearing prey.

- Carnivorous Fish: Carnivorous fish, such as Oscar fish, often have small teeth for capturing and consuming insects and other small animals. (Source: Quora)
- Tooth Replacement: Similar to sharks, some fish, including goldfish, continuously lose and replace their teeth throughout their lives. (Source: Delta Dental)
The location of teeth also varies. Some fish have teeth only in their jaws, while others have them on other parts of their mouths or even in their throats.

Even fish that seem to swallow their food whole, like pike, still possess teeth which aid in securing and initially processing prey. (Source: Quora)
Essentially, the presence and characteristics of fish teeth are wonderfully diverse, reflecting the varied lifestyles and dietary requirements of the vast array of fish species.
