Introduction: A Surfeit of Lampreys,before that, by the ancient Romans, the Māori, and Native Americans. ­Historically, lampreys have also received attention from at least a small group of anatomists and other scientists (including Sigmund Freud), given their “lofty” status at the base of the vertebrate family tree (and their wonderfu

The Taxonomy, Phylogeny, and Distribution of Lampreys, group has an antitropical distribution, with the 37 species of Northern Hemisphere lampreys assigned to the Petromyzontidae, whereas the four species of Southern Hemisphere lampreys are separated into either the Geotriidae (one species) or Mordaciidae (three species). All lamprey species have a bli

The lamprey life cycle includes an embryonic period, a larval period ending with metamorphosis, a parasitic or non-parasitic juvenile period, and an adult reproductive period.

The development of miniaturized active and passive transmitters has led to detailed information on the timing and extent of lamprey migrations. These tools, together with sophisticated laboratory experiments, have provided fertile ground for studies of lamprey migrator

To date, the conservation status of 33 of these species (75 %) has been assessed at a global scal
