Scientists attach shark teeth to a power saw to check the sharpness and durability. It was terrifying when they actually came to know how a shark cuts through and kills its prey.
Scientists attached 4 sets of teeth to a power saw to see how they actually cut through meat.
The teeth of four different sharks that frequent Australian waters were attached onto a power saw and positioned to cut through a large piece of salmon by researches from the Royal Society of Open Science.
The power saw simulates the movement of shark teeth as it has same vigorous and rapid speed like the sharks. They found that some shark teeth are deadly sharp and others a less sharp.
Silky sharks and tiger sharks are the champions when it comes to cutting.
But their teeth dull rapidly after only a few bites.
The bluenose sixgill shark teeth last longer than those of the others tested.
