A great white named Lydia recently made shark history: This weekend, she became the first of her kind known to have crossed from the western to the eastern Atlantic. That happened when she crossed a boundary known as the Mid-Atlantic Ridge. Days later, she's already making more headlines. Researcher Chris Fischer tells the BBC she may be pregnant and headed toward the Mediterranean to have her babies.
Right now, she's about 800 miles from the British Isles, the Daily Mail reports. If she continues in that direction, she could be the first great white officially spotted in the country, Fischer believes. The 2,000-pound, 15-foot creature was tagged a year ago in Jacksonville, Florida, and she's swum more than 19,400 miles since. When she was tagged, she was "super healthy"; Fischer guesses that age-wise, she's in her 20s. You can follow her here.
