What shark has the sharpest teeth? (5 interesting facts)

In this article “What shark has the sharpest teeth?” We will cover the experiment that was performed to know what shark has the sharpest teeth along with some species of sharks and their feeding habits on their prey. We will also cover some interesting facts about shark teeth.

What shark has the sharpest teeth?

Tiger shark and silky shark have the sharpest teeth among all the sharks. Tiger sharks have the sharpest teeth that blunted faster than any other shark’s teeth. These sharks can take down their prey like salmon fish very easily and cut its body into pieces.

Experiment to find out what shark has the sharpest teeth?

An experiment was performed to find out which shark has the sharpest teeth. In this experiment scientists, glued shark teeth on a power saw to see which shark has the sharpest teeth.

The Royal Society of Open Science experimented to see how the shark teeth and the shape of the teeth can affect the cutting ability of the shark’s mouth. They also see the head-shaking ability of different sharks to cut their prey. Most of the sharks use vigorous head-shaking to cut their prey.

The experiment was performed by attaching shark teeth with a 12-inch bimetal blade after grinding the metal teeth on a flat surface.

Teeth of various sharks like bluntnose, tiger shark, silky shark and sandbar were tested. The researchers found out that the tiger shark and the silky shark have the sharpest teeth among all the sharks.

Bluntnose shark has poor cutting abilities as compared to the sand bar, tiger shark and the silky shark. However bluntnose shark teeth were subjected to no wear.

The researchers, Katherine Corn, Jeffrey Brash, Adam Summers, Stacy Farina write, “Some shark teeth are very sharp at the expense of quickly dulling, while others are less sharp but dull more slowly”.

We know that the mammal’s teeth have a wide diversity among species but we can say that sharks are a rival of animals in this case.

A single tooth of a shark can tell us about the species of the shark. This is more common among the predatory sharks. Some sharks have triangular teeth ( Silky shark), some sharks have deeply notched teeth like that of tiger shark. Some sharks have spear-like teeth (mako shark teeth) and some sharks have multi cusped teeth as that of sixgill shark teeth.

Sharks have a variety of tooth morphology and this gives us the idea that how diverse is the creation of sharks and other predatory fishes in the marine land.

They also find out that the teeth of some shark species are subjected to wear and tear more quickly than the others. These sharks have other teeth also but they do not work as quickly as the other teeth of the shark. This gives us the idea that sharks may swallow their prey when the shark teeth are in process of replacement.

Wide-eyed prehistoric shark ( Ferromirum oukherbouchi)

Imagine that you are swimming in an ocean when you see a predatory shark. It moves towards you and stretches its lower jaw and exposes the lower sharper teeth that were first hidden.

Scientists have discovered such a nightmarish trait fossil about 370 million years older. According to the new study, they found that a shark named Ferromirum oukherbouchi, was living in the waters of Morocco almost 370 million years ago. This shark had the ability to rotate its jaw inward when the mouth is closed and rotate it outwards when the mouth is open.

We know that in sharks the older teeth are displaced by the new teeth. This shark has a row of new and sharper teeth next to the row of old teeth. When the new teeth grows it curves towards its tongue.

When this shark opened its mouth the cartilage at the back of mouth flexed and the sides of the jaw were folded downward exposing the new and sharper teeth of the shark.

This shark has a slender body measuring 13 inches. This shark has large and wide eyes and covers 30% of the brain. It has a triangular and short snout.

The jaw and the hyoid arch of the shark were preserved in 3D which will give us the idea of shark jaw and teeth. A 3D model of the jaw was created. The scientist performed computed tomography and revealed that the new and sharper teeth were not fused to the bottom of the jaw and instead were flexible and movable when the cartilage at the back of the jaw moved.

Linda Frey, a lead study author said, “Through this rotation, the younger, larger and sharper teeth, which usually pointed toward the inside of the mouth, were brought into an upright position. This made it easier for animals to impale their prey.”

After sizing and cutting the prey with the inner sharp teeth the shark closes its mouth. When the shark closes its mouth the prey is pushed back to the throat and the inner sharper teeth that were exposed to the environment rotate back to the bottom trapping the prey in the shark mouth. This type of jaw movement was not seen in any kind of fish. 

The 3D model gives us the idea of the hidden shark teeth. In early studies, the shark teeth were not preserved carefully and the standard protocol was not followed that is why they don’t see such creatures.

The 3D model also gives us the idea of the tooth placement and assembly of the teeth in the jaw. This also helps us to understand the evolution of jaws over time in the shark species.

This was a breakthrough in the shark study to find out what shark has the sharpest teeth.

Great white shark

The great white sharks are the largest predators on earth. These sharks live in coastal waters and weigh 4200 pounds and length of 20ft. They have scary and sharp teeth in the animal kingdom. 

They have 3000 teeth in their mouth at a time. When a tooth is lost another tooth slides forward and there grows a new one. There is growth of around 30000 teeth in their entire life. Make sure you don’t get trapped in this shark mouth.

These sharks have no predators except orcas. Among all the species of sharks, they have a robust jaw and sharp big pointed teeth. The front teeths of the jaw are the sharpest and they do most of the cutting and sizing.

They have a bite force of 669 PSI. PSI stands for pound per square inch. It is the force applied by the shark teeth on 1 square inch of the surface or the body of the prey.

The scariest teeth in the animal kingdom are of a fish nicknamed as Vampire fish. The Payara fish is a carnivore fish having canine teeth. They possess two fangs emerging from the lower jaw straight into the upper jaw and the head. The head has two negative spaces in which these two fangs rest when they are not utilized.

The shark having sharpest teeth are deadly and you should keep a distance from them as they can quickly tear you into pieces.

Interesting facts about sharks

Some sharks have 50,000 teeth during their lifetime. I know this sounds crazy but it is the truth. The shark teeth are not that strong and most of the sharks have 300 teeth in different stages of their life.

Their teeth do not have roots and that is why they easily fell out and you can find them on beaches. Sharks can easily replace their lost teeth with the new ones.

All the sharks have layers or rows of teeth. On average the shark has 15 rows and most of them have only 5 rows of teeth. The bull shark has 50 rows of teeth and each row has 7 teeth. This means they have 350 teeth at a time. That is why we do not mess with the bull shark.

The shark’s upper and lower jaws are movable. Most of the mammal’s upper jaw is fixed with the skull but in case of sharks, the upper jaw is not attached with the skull that is why they can stretch their mouth to capture their prey. The movable jaw also gives them the ability to move their mouth forward while capturing prey.

Sharks have different teeth according to their diet. Those sharks that prey on other fishes have scary sharp teeth. Other smaller sharks have a filtering system rather than the chewing system. They have teeth much like a whale that can filter the water. They do not have sharp teeth as that of other sharks.

The predator shark has the sharpest teeth as compared to other sharks because they need to cut the thick skin of the other fishes. Often the sharp having sharpest teeth are very fast.
