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.
Agnatha, which is a parphyletic superclass of jawless fish in the phylum chordata, have no actual existing stomach of any such. But they do have a tail and a caudil fin.
Jawless fish are generally marine and also will be found either on thier host's bodies or for hagfish, in dens on the on the substrate.
