Blue walleye

Extinct subspecies of fish

The blue walleye, also called the blue pike, was a unique color morph of walleye which was endemic to the Great Lakes of 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.
