A giant bowhead whale caught off the coast of Alaska had a harpoon point embedded in its neck that showed it survived a similar hunt ? more than a century ago.
Biologists claim the find helps prove the bowhead is the oldest living mammal on earth.
They say the 13-centimetre arrow-shaped fragment dates back to around 1880, meaning the 50-ton whale had been coasting around the freezing arctic waters since Victorian times.
