Lampreys are parasitic and feed on a variety of animals, including fish, turtles, and even other lampreys. They are not typically considered to be a threat to humans, but there have been a few cases of lampreys attacking people.
How do lampreys feed?
Lampreys are jawless fish that have a unique feeding mechanism. They have a round, sucker-like mouth with a rasping tongue that they use to attach themselves to their prey. Once attached, they use their tongue to rasp away at the skin and flesh of their prey, creating a wound. They then secrete an anticoagulant to prevent the wound from clotting, and they use their tongue to suck up the blood and body fluids of their prey.
