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]
Lethenteron appendix, the American brook lamprey, is a common non-parasitic lamprey in North America. [4] In adults their disc-like mouths contain poorly developed teeth, useless for attaching to a host.

Sea lamprey is the most sought-after species in Portugal and one of only two that can legally bear the commercial name "lamprey" (lampreia): the other one being Lampetra fluviatilis, the European river lamprey, both according to Portaria (Government regulation no. 587/2006, from 22 June).
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.
Lethenteron reissneri, the Far Eastern brook lamprey, is a species of lamprey. Immature L reissneri are parasitic, but shift to a non-parasitic feeding strategy upon reaching maturity. [ 2 ] It is found in lakes and rivers in China, Japan, Korea, Mongolia, and the Russian Far East. [ 3 ]
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).
Mordacia praecox, the Australian brook lamprey or nonparasitic lamprey, is a freshwater species of southern topeyed lamprey that occurs in south-eastern Australia. It has a thin eel-like body around 12 to 15 cm (4.7 to 5.9 in) long, with two low dorsal fins on the back half. The skin is dark blue above and grey below.
