The lamprey or the sea  vampire is present in the Galician, North Atlantic and western Mediterranean rivers. It is a vertebrate fish without jaw (agnates) like the mixines. Also, they do not have scales but a smooth skin. They are animals without evolving since the Paleozoic in which the first vertebrates appeared in Pangea (the only primary continent divided over the years in the current continents). The lamprey is for many an authentic delicacy, as it was in the Middle Ages and for the Romans, but not for others like the Japanese, Americans or Canadians. As the lamprey, due to its devouring capacity, can hunt a large quantity of fish per day, as well as trout and tuna, reducing their fishing profit. He can live up to 18 years and is called the sea vampire because he is a parasitic fish that feeds by sucking the blood of his victims.

In Galicia they are fished in the river Miño and in the Ulla river with fishing and nets, the local festivities in their honor being abundant like that of Pontecesures, Rois, Arbo ... which are celebrated in March-April.

Typical recipes of the lamprey are:

Lamprey à la bordelesa, lamprey with chocolate, lamprey with pickled vegetables, lamprey pie, etc.
