Why Lampreys Attack Humans?

If sea lampreys attacked humans the same way they go after fish, they would be things of horror stories. They're parasites with a mouth designed to rasp a hole in a fish and suck out vital fluids. ... "They're not going to attack humans; they're not going to parasitize humans," said Stockwell.

Do lampreys hurt humans?
