Have you ever wondered, “Do goldfish have teeth?” and if they can bite? Look no further! In this informative blog post, we will explore the intriguing dental anatomy of goldfish, including the function and location of their teeth. Prepare to gain a whole new understanding of your aquatic companion and be amazed by their dental structures.
Do Goldfish Have Teeth?
Absolutely, goldfish do have teeth! While humans and many other mammals have teeth situated in the front of the mouth for chewing, goldfish possess a unique set of teeth known as “pharyngeal teeth”.
These special teeth are located not in the mouth, but in the throat, or pharynx, of the goldfish. The primary function of these teeth is to crush and grind food particles before they move further down into the digestive system. Essentially, the goldfish starts “chewing” its food only after the food has passed through its mouth and reached the throat.
Understanding the dietary needs and feeding mechanisms of goldfish is crucial for their well-being. Sadly, many goldfish suffer and even die due to inadequate feeding practices, such as improper diet or incorrect portion sizes. Being aware of their unique mouth and teeth anatomy can help you make better decisions in terms of what and how to feed them.

Where Are Goldfish Teeth?
If you’ve ever attempted to search for teeth in your goldfish’s mouth, you may have been perplexed by the lack of visible teeth. However, fear not, as their teeth do exist, albeit in an unexpected location. Unlike most animals, goldfish have teeth positioned towards the rear of their mouths, in a region called the pharynx. Interestingly, the pharynx is a shared anatomical feature among various organisms, including humans. This means that, in a sense, you have something in common with your goldfish when it comes to anatomy.
Referred to as “pharyngeal teeth” these structures serve a specific purpose: grinding food into smaller, more easily digestible particles as it proceeds through the digestive system. This unique dental adaptation allows goldfish to effectively break down their food for efficient digestion.
Why do goldfish need teeth?
You might be wondering why goldfish, who are not predators, would need teeth at all. The answer lies in their evolutionary background and their diet. Goldfish are part of the Carp family, and many of their cousins within this family also possess similar dental structures.
Because goldfish are not predatory fish, their dental structures have not evolved for capturing or tearing apart prey. Instead, their teeth serve a specific function closely tied to their diet and way of life.
Their pharyngeal teeth are primarily designed to break down the types of food they commonly consume, such as plant matter and small aquatic organisms, into smaller, easily digestible particles. This grinding action aids the digestive process, allowing for better nutrient absorption once the food reaches the digestive tract.
Do Goldfish Lose Their Teeth?
Goldfish undergo a continuous process of tooth loss and regrowth throughout their lifespan. As their old teeth fall out, new teeth are already growing behind them, poised to take their place.
In the case of a bare-bottomed aquarium, it is possible to spot the discarded teeth of goldfish on the tank floor. Some individuals have even captured videos showcasing the teeth collected from their goldfish. If you happen to observe your fish at the right moment, you might even witness them spitting out an old tooth! This fascinating phenomenon highlights the ongoing cycle of tooth replacement in goldfish.

Can goldfish bite?
It’s common for people to be taken aback when they learn that goldfish have teeth. This newfound knowledge might even raise concerns about potential finger-biting incidents during feeding time.
However, there’s no need to worry. Goldfish teeth are not sharp, and they are incapable of biting people. In fact, their teeth are quite flat, resembling human molars, and their purpose is to crush and grind food rather than to cause harm.
Does a Goldfish Bite Hurt?
If you’ve felt a little nip from your goldfish, you may be taken aback but there’s no reason to be alarmed. A goldfish nibble is more of a curious investigation than an aggressive act. They’re basically trying to figure out if you’re something edible. You’ll be relieved to know that a goldfish’s nibble is harmless; it won’t break the skin or even leave a mark.
Is goldfish teeth sharp?
No, goldfish teeth are not sharp. They are flat and fairly smooth, designed to grind food into a digestible form. The exact evolutionary reason behind this tooth shape is not fully understood. However, it’s widely believed that the flatness of their teeth could be an evolutionary leftover from their Carp ancestors.
Do other types of fish have teeth?
Absolutely, most fish species have some form of dental structure. However, the shape, size, and location of these teeth can vary widely. For example, sharks have razor-sharp teeth designed for tearing flesh, while piranhas have small, pointed teeth for similar purposes. On the other hand, Sheephead fish have human-like teeth that are quite startling to look at.
So there you have it the answer to the intriguing question, “Do goldfish have teeth?” is a resounding yes, but in a way that’s uniquely fascinating. From their pharyngeal teeth designed for grinding food, to their harmless nips that won’t hurt a finger, goldfish offer a world of biological wonders right in your own aquarium.
