| phylum | Chordata | The blue walleye(Sander vitreus glaucus), also called the blue pike, is an invalid subspecies of walleye alleged to have inhabited the Great Lakesof North America. Morphometric studies led biologists to classify the blue walleye as a separate species in 1926, although it was later downgraded to a subspecies. Listed as an endangered species by the United States in 1967, it was declared extinct in 1983.
Genetic analyses conducted in the 21st century show that blue walleye were not genetically different from yellow walleye, rendering the taxon invalid. For more information, visit the Wikipedia entry Get back to Perches |
