A great white shark named Lydia has surprised researchers by heading north into Canadian waters as temperatures drop.

"Based on what we know about the historical distribution of white sharks, Lydia's movements into Canadian waters are not that surprising. What does surprise me is that she is going there this time of year when we would expect her to be moving south," Massachusetts Division of Marine Fisheries senior scientist and program manager Gregory Skomal said Monday on the Facebook page of the shark research group Ocearch.

The 2,000-pound, 14-foot female white shark was tagged off the coast of Florida in March so researchers could track its movements.

She made her way into Placentia Bay, N.L., on Monday. The group issued a warning to residents of Marystown, just in case any of them decided to go in the water.

Ocearch founder Chris Fischer said they thought maybe they'd see Lydia in Atlantic Canada in late summer, but not late October.

"It's shocking to our team," he said in an interview Tuesday. "Where's she going to go from here?"

On Saturday, Simon Thorrold of the Woods Hole Oceanographic Institution also questioned why Lydia is taking a break in Canada.

"What is she doing so far north, so late into the fall? Lydia seems to enjoy dispelling every generalization that we come up with in terms of white shark migration in the North Atlantic," he said in a statement on the Ocearch Facebook page.
