A great white shark known as Lydia is about to complete a mission no other great white has accomplished before: crossing the Atlantic Ocean.
In March 2013, 15-foot-long Lydia was tagged by satellite as part of the Ocearch project in Florida. She was last spotted about 1,000 miles from the coasts of County Cork in Ireland and Cornwall in Britain. Researchers tracking her progress said she has traveled 380 miles in just 72 hours. If she maintains that pace and direction, she'll reach British waters in two days.
So far, Lydia has traveled upwards of 19,000 miles.
"Although Lydia is closer to Europe than North America, she technically does not cross the Atlantic until she crosses the Mid-Atlantic Ridge, which she has yet to do," Gregory Skomal, senior fisheries biologist with Massachusetts Marine Fisheries, told the BBC.
Scientists are still unsure where her journey will take her next, but Europe and the coast of Africa are in the cards.
