Rare Patagonian Toothfish on Top of the World

LONDON (Reuters) - A Patagonian toothfish that normally lives in the icy
waters around Antarctica has hitched a ride to the top of the world and
turned up off the coast of Greenland, scientists said Wednesday.

Fishermen were puzzled by the discovery of the 5 foot, 11 inch, 154-pound
toothfish, the first ever seen in the northern hemisphere.

The furthest a Patagonian toothfish had previously strayed from home was
6,000 miles to the Atlantic Ocean near Uruguay.

But scientists at the University of Copenhagen believe the fish captured off
the coast of Greenland caught a very deep, cold ocean current to migrate
underneath warm tropical waters across the equator.

"This strategy would enable the fish to travel all the way from Patagonia to
west Greenland," Peter Rask Moller said in a report in the science journal
Nature.

He and his colleagues believe the theory could explain how the same species
of cold-loving fish can occur at both the North and South poles despite the
warm waters in between.
