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.

Lampreys may spend up to eight years as ammocoetes, [57] while species such as the Arctic lamprey may only spend one to two years as larvae, [58] prior to undergoing a metamorphosis which generally lasts 3–4 months, but can vary between species. [59] While metamorphosing, they do not eat. [60]
The sea lamprey (Petromyzon marinus) is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". In its original habitats, the sea lamprey coevolved with its hosts, and those hosts evolved a measure of resistance to the sea lampreys.
A study of Pennsylvania streams found that two of the six species of lampreys normally found breeding in the streams were not there. [10] One of the species not found was the northern brook lamprey. It is speculated that the main reason for population decline is due to the presence of sea lamprey and the lampricides used to be rid of them. [10]
We’ve all seen lists of “good” and “bad” foods. While some foods are more nutritious than others, this demonization of certain foods can be harmful—and inaccurate. Take vegetables as ...
Which is larger in size (15 – 18 cm). The Morrison Creek lamprey is able to feed after it becomes an adult [6] unlike the western brook lamprey which can only feed in its larval stage. [6] [7] The western brook lamprey is Not at Risk (Yellow List) and does not have a Species at Risk Act. [7]
