That's the name given to a great white shark that was tagged in New England and has been spotted off Florida's coast. This week, she's been tracked to the waters off Melbourne.
The group OCEARCH first tagged Katharine in 2013 and she first started showing up along the Florida coast a year later, as far south as the Keys.
She was off the coast of Jupiter and Delray Beach in January.
