A 2,000lb shark may be making its way to Swansea Bay and experts believe she is pregnant.
The hulking great white shark which has been sighted 800 miles away from Britain could be pregnant - meaning a whole school of potentially killer fish.
The shark, which has been named Lydia, has become the first of its species, which are endangered, to be recorded crossing the Mid-Atlantic Ridge and she may be heading for our coastline with the intention of giving birth here.
The most recent tracking information on the shark - from Ocearch
Lydia has covered more than 19,400 miles in the past year since being fitted with a tracking device as part of a groundbreaking marine life study and experts say they are shocked by her recent dash towards Europe, swimming 313 miles in the past 72 hours alone.

Chris Fischer, expedition leader and founding chairman of the Ocearch shark tagging project, said: "If I had to guess, I would guess that Lydia is pregnant and that she has been out in the open ocean gestating her babies and that this spring she will lead us to where those baby white sharks are born - the nursery."
