A great white shark could be heading for our shores.
Scientists are tracking the movement of the 17ft female shark, named Nukumi.
She weighs 3,541lb and she may arrive in the UK this summer.
She usually swims up and down the coast of the USA but, has turned east and she is currently crossed the Mid-Atlantic Ridge.
Her progress is being charted by Ocearch, a non-profit research group.
A GPS tracker has been attached to her fin and you can track her here.
