The lamprey it seems is not only a curious looking creature but an interesting organism to help biologists understand the evolution of the jaw. I am told that it also makes a fine dinner, something which Henry I would at one time have attested to, before it was too late! I caught the following guy mournfully looking at the passers by in the old town of Santiago de Compostela last week.
