Several experts employed by RAVON, a knowledge institute for reptiles, amphibians and fish, happened to be fishing nearby and confirmed his suspicions: it was indeed a sea lamprey. Thomas caught the slippery animal and released it in a creek nearby, so it can travel up the Meuse river via the Steurgat. It was an impressive if somewhat bizarre encounter.
