A Whale of a Sliver

A harpoon tip found lodged in a bowhead whale off the coast of Alaska gives scientists a good idea of the life-span of these elusive creatures.

An old harpoon tip was discovered lodged in the body of a whale recently killed by Eskimo hunters in the Arctic Ocean. Historians date the weapon to be roughly from 1890, which means the bowhead whale was at least 125 years old when it was killed.
