Great white sharks may have ended up in the Mediterranean after they managed to get lost.
According to a report by the BBC, a study of shark DNA has found that the Great whites found in the Mediterranean are closely related to those from Australia and New Zealand.
It's thought that they may have first arrived from the seas around Australia about 450,000 years ago due to a migratory mistake by a group of pregnant females that simply took a wrong turn. At a time between ice ages, a changing climate may have affected the currents, pushing the sharks off course.
The species then remained in the area because it returns to spawn where it is born.
Les Noble of the University of Aberdeen told BBC News: "They're like salmon - where the pups are dropped, they recognise as their home - that's where they always return to.
"It may be then that just a few shark pups - or perhaps just one - born in the Mediterranean due to a migratory wrong turn, returned to establish the species there."
