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 southern brook lamprey secretes mucus from its body to form a tube leading to the entrance of the burrow and to provide support for the burrow. [10]

The brook lamprey is a common, non-parasitic species that is endemic to Europe. [1] Adult brook lampreys measure from 12 to 14 cm (4.7 to 5.5 in). The body is highly elongated and dark blue or greenish above, lightening to yellowish off-white on the sides and pure white on the ventral side.
Lampetra is a genus of lampreys in the family Petromyzontidae.. Phylogenetic studies indicate that this genus as presently defined is polyphyletic, with species of this genus from western North America forming a clade that forms the sister group to Lethenteron, Eudontomyzon, and Lampetra sensu stricto (eastern North American and European species).
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 ...
The eggs of the American brook lamprey (ABL) are white, sticky, and small, measuring about 1 mm (0.04 in). When they hatch, the embryos are small as well, measuring less than 5 mm (0.20 in); they are white and wormlike. Within a month they take on the larval appearance.

Mordacia is a genus of lamprey, the sole genus of the family Mordaciidae, also known as the southern topeyed lampreys. The family Mordaciidae is most closely related to the lamprey family Geotriidae , which has a similar Gondwanan distribution, and both families diverged during the Early Cretaceous .
