During the larval stage, the southern brook lamprey inhabits a distinct micro habitat involving relatively slow moving water and a sandy substrate. [7] The consistency of the substrate is vitally important to the Southern brook lamprey because during the larval stage, the lamprey burrows into the substrate using its oral disk as an anchor. [10]

The western brook lamprey and river lamprey have been considered a clade separate from the other western U.S. lamprey species. [12] However, more recent genetic research suggests the western brook lamprey would be better categorized as a member of a Lampetra ayresii species complex. [11] Additional research that crossbred river lamprey and ...
