Lampreys (Petromyzontida)

Lampreys or lamprey eels are often classified as the sole surviving representatives of the Linnean class Cephalaspidomorphi (IUCN 2010; Wikipedia-bijdragers 2010; Wikipedia contributors 2010). Fossil evidence now suggests that lampreys and cephalaspids acquired their shared characters by convergent evolution (Forey and Janvier 2000; Janvier 2008, Wikipedia contributors 2010). As such, many newer databases, papers and books such as the fourth edition of Fishes of the World (Nelson 2006) classify lampreys in a separate group called Petromyzontida (or Hyperoarthia) (Wikipedia contributors 2010).

The subjoined table shows the lamprey species that recently became globally extinct. There are no known extinct subspecies yet.
