The fish with teeth are:

1. The carp, herring, and grass carp that we often see in the fish market do not have teeth in their mouths, but they do have throats. tooth. The throat teeth of carp fish are particularly developed, and their function is to cut or crush food. The shapes of throat teeth are also different. Some teeth are flat and thin, some are finger-shaped, some have sharp tips, some have hooks, some have serrated surfaces, and some are similar to mammalian molars. These different shapes The teeth are closely related to the feeding habits of fish. ?

2. Fish have teeth, and different fish have different teeth. There is a ferocious fish in the ocean called Bansiao Hao. It has a slender body and swims extremely fast. Its teeth are not only sharp, but also have small hooks at the tips. If it bites any animal, its wounds will not heal easily. Moreover, stained teeth are also toxic. Shark teeth vary greatly in size and shape, ranging from elongated and cone-shaped to flat and triangular. The teeth of the nurse shark are in another shape. Its teeth are pavement-shaped. All of these teeth can be used and are very suitable for grinding food. The tiger shark's teeth are even weirder. It actually has teeth of different shapes on the same jaw, which is rare among fish. The teeth in the upper jaw are pointed and cone-shaped, and the teeth in the lower jaw are pavement-shaped, which can crush or crush hard-shelled animals. The "high jumper" ray that lives in the ocean also has strange-looking teeth. In its large mouth, there are several hexagonal teeth in the middle. The teeth on both sides are flat and stone-like, and no matter what shape they are, The teeth are arranged in three rows, so it can eat everything from fish to crustaceans.

3. The pike’s teeth are even more chilling. A mouth full of sharp teeth of different shapes. The teeth on the front jaw are very small. When it catches food, it uses the thin and dense teeth at the top of the mouth to chew it slowly and taste it. The teeth on both sides of its lower jaw grow large and straight, and are attached to the bones by ligaments. These teeth can be tilted toward the esophagus and recumbent to enhance food swallowing. And because these teeth cannot lie outward, it is difficult for prey to escape once swallowed.

4. The teeth of salmon are sharp and long, like many awls placed together. Some people describe its teeth as a living meat slicer, which can cut the fish into many pieces. Many animals are afraid of its teeth, so wherever the salmon goes, the water is in a mess.

5. Sea bream takes shellfish as its main food, so it has two shapes of teeth in its mouth. The front teeth are cone-shaped and can be used to cut food; the teeth on both sides are molars and are used to crush food.
