The shark has the strongest jaw

Cow sharks have the strongest bite of sharks, many times the force needed to kill and eat prey.

The adult cow shark takes the bait with a force of up to 6,000 newtons (N), more powerful than white sharks or hammerhead sharks, according to research on jaw and shark jaws published in Zoology magazine.

Scientists are not sure why the bull's shark is so powerful, much more powerful than the force needed to kill and eat prey.

Maria Habegger, a graduate student at the University of South Florida, USA and colleagues studied the bite force of 13 species of sharks and fish with relatives close to them, from 1mfish fish - relatives with regular sharks. living on the seabed, eating crabs or boys, up to the giant 6m long white shark - eating fish and sea animals like seals or dolphins.

Previous studies have shown that sharks possessing large bodies often have strong strikes. Habegger said on BBC: "We think big sharks will have strong bats like giant white sharks, tiger sharks or bull sharks. They often hunt big prey like dolphins, turtles or even sharks. Other, should follow the natural mechanism, they must create very large bite force ".

However, according to the study, smaller fish such as ratfish also have very strong bite force in proportion to body size, probably because they have to crush the prey of the prey.

Researcher Habegger said, although large sharks create strong bats, how important the bite force is when considering the ratio of bite force and body weight.

She and her colleagues studied the jaw muscles and calculated the force they created when closing the jaw, then used the calculation tool to remove body mass, creating a fair comparison between species. shark.

As a result, cow sharks produce the strongest bite force among the studied sharks. In addition, the bite force of bull shark also changes according to its life cycle. Young bull sharks have stronger beats than older ones. This gives them an advantage over other competitors, helping them to hunt for more diverse prey as a child.

According to the study, most bull sharks produce a force of nearly 6,000N in the back jaw and 2,000N in the previous jaw.

Experts say that there is no need for such a powerful force to penetrate fish skin or even pierce bones. Perhaps the health of cow sharks is used to crush tortoise shells or to hunt in dark areas where cow sharks reside.

In a restricted-vision habitat, hunting is more difficult than other waters, so to ensure that you don't lose a meal, the shots must be really strong to finish off your prey.

Cow sharks with the scientific name Carcharhinus leucas, belong to the Carcharhinidae shark family, often living in warm and shallow waters. They can be up to 3.5 meters long, have a very strong and aggressive head.
