Bizarrely, scientists have found that sharks in the southern Indian Ocean have a remarkable ability to navigate using the shape of their teeth.
The team, led by the University of Queensland’s Professor Peter Loh, and funded by the Australian Research Council, used a technology developed by Drs.
Mark Smith and Tom Williams to see if the sharks’ teeth could help them find their way.
The researchers first examined tooth impressions from a shark that lived at a remote island called Kew, in the Indian Ocean.
They also found that the sharks used the shape and size of the tooth to guide their movements.
They then compared that with a shark known as a “shark tooth” — a shark whose teeth are hollow.
They found that this shark was much more efficient at finding its way in the ocean, as opposed to other sharks.
“Our study has shown that these sharks have evolved the ability to find their own way using the shapes and size in their teeth,” said Loh.
The scientists hope that their findings will be useful to people with mental health issues, as well as in shark conservation efforts.
“These sharks are really fascinating because they are really intelligent,” said Professor Loh.
“They’re really smart because they have this ability to detect the direction of their prey and they are able to use the shape, size, and position of their tooth to make the correct choice.”
It’s a remarkable trait.
So far, the only other shark known to have the ability is a shark called a shark shark, which is a member of the same family of sharks as sharks like the hammerhead and blue shark.
