Diversity of Cypriniformes

With 4,000 species, Cypriniformes is the most diverse monophyletic order of vertebrates. About 1 in 3 (30%) species of freshwater fishes, 1 in 8 fishes (12%), and 1 in 17 vertebrates (6%), is a cypriniform. Cypriniforms are most diverse in the least-explored parts of the tropics, and we estimate the number of species to be much larger than now recognized, closer to 4,500-5,000.

This is the primary page opening to two very large research initiatives on Cypriniformes fishes: the All Cypriniformes Species Inventory (ACSI-2), funded by the U.S. National Science Foundation DEB-1022720 (Dr. Lawrence M. Page, University of Florida), DEB-1023403 (Dr. Jonathan Armbruster, Auburn University), and DEB-1021840 (Dr. Richard L. Mayden, Saint Louis University )and The Cypriniformes Tree of Life (CToL), funded by the U.S. National Science Foundation EF-0431326 (Drs. R. L. Mayden, R. M. Wood, and N. Aspinwall).
