No, lampreys are not dangerous. Though you may see people coming out of lakes or freshwater ponds with them attached to their body, it does not harm you. Sometimes lampreys attach to objects to fight the current, it is not sucking out your blood. I imagine that humans don't taste very good to lampreys as they suck the blood of FISH. Not humans. Though I do have to say they look pretty scary... hope this helped!

Phanerogamic parasites are plants that derive nutrients and water from other plants, known as hosts. They belong to the group of parasitic plants, such as mistletoe and dodder, which attach themselves to the host plant to obtain the necessary resources for survival and growth. These parasites have specialized structures, such as haustoria, that allow them to penetrate the host's tissues and extract nutrients.
