Classification
Vladykov and Kott (1979) proposed classifying the Northern Hemisphere lamprays into three subfamilies: Petromyzontinae, Entospheninae and Lampetrinae.[3][4] Also Carim et al. (2024) proposed a genus Occidentis for western North American ‘Lampetra’.[5][6]
- Subfamily Petromyzontinae
- Ichthyomyzon
- Petromyzon — sea lamprey
- Caspiomyzon
- Subfamily Entospheninae
- Subfamily Lampetrinae
