One-tonne great white shark named 'Lydia' moves closer to Britain
A deadly great white shark named Lydia has become the first of her species to cross the Atlantic Ocean
It may not be safe to go back into the water.
A deadly great white shark named Lydia has become the first of her species to cross the Atlantic Ocean - and is on course to reach the shores of Ireland.
US scientists for Ocearch have been tracking the one-tonne man-eater for 19,500 miles as it makes its journey across the Atlantic from Florida.
The 15ft beast is the first tagged shark to cross the Mid-Atlantic Ridge - the boundary between west and east.
Last week it was predicted the great white would reach Britain over the weekend but the predator took a detour.
She is now 780 miles off the coast of Ireland and Cornwall.

Dr Gregory Skomal, senior fisheries biologist with Massachusetts Marine Fisheries said Lydia was now closer to Europe than North America.
Lydia's movements can be tracked on Ocearch's website.

The Ocearch project tags sharks to learn more about their movements.
The team used a 34,000kg hydraulic platform to hoist Lydia from the water in order to fit the tracking device.
Adult great white sharks are known for their migratory patterns.
A shark named Nicole was tracked swimming from South Africa to Australia and back in nine months in 2004 - a total journey of more than 12,000 miles.
