Sea lamprey

Just like other lampreys, sea lampreys have a monster-like suction mouth with rows of small grating teeth. Using these teeth, they clamp onto large fish to suck their blood. This is necessary for survival. They attach themselves so tightly that the victims are not usually able to shake them off, despite the suffering they incur from these parasitic fish. The wounds made by the lampreys can cause death in the victims.

  • Distribution and habitat

    The sea lamprey swims in the Atlantic Ocean, coastal waters of Europe and North America. It only uses Dutch rivers when migrating to Germany. It does not lay its eggs in the Netherlands.
    Sea lampreys are born in fresh water, where they live in the mud as blind and toothless larvae for several years. Only after turning adult do they migrate to the sea. Therefore, it is important that their migration route back and forth is not blocked by dikes and sluices.
