All the Queen's eels

For centuries the people of Gloucester, England, have sent a lamprey pie to the reigning royals in celebrations of important occasions. Due to declining numbers, the pie for the Queen's Diamond jubilee will be made from imported lampreys.

This year's lampreys will be supplied by Canada and come from the Great Lakes.

The lamprey is an eel-like fish whose roots as an English delicacy go back to at least the 12th century.
