Hagfish live off dead carcasses of animals sinking to the ocean floor, sliding in and out of the bodies and feeding on both inside and outside. They produce ridiculous amounts of slime to aid them with this.
Lampreys latch onto fish with their circular, toothy mouths and scrape away scales and flesh with a tongue that´s also covered in teeth. They are considered parasites.
