Abstract

Of all the existing vertebrates (more than 60,000 species), practically half (32,000) are fish. Within this group, more than 15,000 are strictly freshwater while only 225 are diadromous. Diadromy is a typical characteristic of species that perform migrations from the seas to the rivers, or vice versa associated with spawning. Modern lampreys (Petromyzontiformes) are one of the two surviving lineages of jawless fish (Agnathans), in addition to the hagfish (Myxini). Both lineages have survived at least four of the five mass extinctions that have occurred in the history of the Earth. These lineages diverged from a common ancestor.
