Lampreys, belonging to the family Petromyzontidae, are distinctive jawless fish that exhibit a unique parasitic lifestyle during their adult stage. Some well-known examples of lampreys include:
  • Sea lamprey (Petromyzon marinus): Native to the Atlantic Ocean, this species is notorious for its parasitic impact on commercial fish stocks in the Great Lakes.
  • Pacific lamprey (Entosphenus tridentatus): Found along the Pacific coast of North America, this species plays a vital role in the ecology and culture of indigenous peoples.
  • Brook lamprey (Lampetra planeri): A nonparasitic species residing in freshwater streams, recognized for its contribution to nutrient cycling.
While 'Atlantic lamprey' is a common name, the primary recognized lamprey species include Sea lamprey, Pacific lamprey, and Brook lamprey.
