Studies that focused on closely related lamprey species (I. fossor) found that the guts of larval lampreys contained 97.9% organic detritus, 2.12% algae, and 0.09% bacteria. [6] After metamorphosis into the adult phase, southern brook lampreys do not feed but rely on stored fat reserves accumulated during the larval stage for energy and nutrients.
Adult carnivorous lampreys are the most well-known species, and feed by boring into the flesh of other fish (or in rare cases marine mammals) to consume flesh and/or blood; [9] but only 18 species of lampreys engage in this predatory lifestyle [10] [11] (with Caspiomyzon suggested to feed on carrion rather than live prey [9]).
