Google has been forced to reinforce cables deep under the ocean that carry internet traffic around the globe after they were attacked by sharks.
The fibre optic cables are protected by a series of layers, so they are not damaged by impact or movement.
However the Guardian reports that sharks, possibly attracted to the magnetic field created by the high voltage of the cables have been biting them, forcing engineers from the web giant to reinforce the cables with extra material.
The company released surveillance footage, showing a shark gnawing on a cable.
Older copper cables have not been attacked, and experts believe that the magnetic energy given off by the newer cables confuses the sharks, as it resembles that created by fish.
