The news that a nineteenth century tool has been retrieved from a live whale is strange, but apparently true:

A 50-ton bowhead whale caught off the Alaskan coast last month had a weapon fragment embedded in its neck that showed it survived a similar hunt — more than a century ago. Embedded deep under its blubber was a 3 1/2-inch arrow-shaped projectile that has given researchers insight into the whale's age, estimated between 115 and 130 years old.

"No other finding has been this precise," said John Bockstoce, an adjunct curator of the New Bedford Whaling Museum.

Calculating a whale's age can be difficult, and is usually gauged by amino acids in the eye lenses. It's rare to find one that has lived more than a century, but experts say the oldest were close to 200 years old.

The bomb lance fragment, lodged a bone between the whale's neck and shoulder blade, was likely manufactured in New Bedford, on the southeast coast of Massachusetts, a major whaling center at that time, Bockstoce said.
