Do Trout Have Teeth?

If you’re a fishing newbie or fanatic, you may have wondered do trout have teeth?

Well, let me break the ice for you; yes they do! Most species of trout fish have teeth; however, the location of these varies in each species of trout. Larger and mature trout have strong jaws and have more power and aggressiveness to feed on their prey. Smaller trout also have teeth however due to their maturity; they are much smaller and have less power in their jaws at an early age.

Type of Teeth on a Trout

Most trout species have vomerine teeth which are found in the middle of the upper jaw. These teeth help the fish to grab and hold on the food they are trying to eat. It also helps it to take the food down the trout’s throat. A great way to recognize a trout from a salmon is by using these vomerine teeth. A salmon would have a single row of teeth whereas a trout would have two. Maybe when you next visit your local fish mongers or supermarket, you can take a look and learn something new.

Generally, two types of teeth are found in trout. Rainbow trout have teeth located along the roof of the upper jaw whereas brown trout also known as cutthroat trout would have teeth located along the gill and behind the base of the tongue. Understanding the location of teeth can also help you identify the particular species of the trout.

How Do Trout Prey and Target Food

Like other predatory species in freshwater, trout are extremely good hunters. Trout tend to stalk their prey and would follow their prey quite slowly. The trout would let the natural wave-current or movement of the water be it a river and stream do the work and let it bring the prey close to the mouth of the trout. Once the prey is close enough, the trout would simply flare up its gills and would suck the prey inside. The prey would then be “tasted” by the trout between the roof of the mouth and the tongue. It would either be expelled or engulfed in if the trout likes it. This whole process occurs very fast, and not so visible to the naked eye.

Trout’s Teeth as Defense Mechanism

Not only do trout teeth help in grasping and engulfing their prey, but they also serve the purpose of choosing the right prey.

Trout like to eat crustaceans as well as a variety of insects and in case, the trout engulfs a crayfish it needs to be careful as crayfish have spikes and if engulfed from the wrong direction, it can result in the death of the trout by choking it. Therefore, the grasping of prey system of the trout helps it to turn the crayfish around so tail first into the throat. This way it avoids any potential damage to itself and can digest its prey safely.
