What is Michigan's Longest Living Animal?

Michigan's longest-living animal is the lake sturgeon. According to Sea Grant Michigan, lake sturgeon live longer than any other fish species in Michigan. Males get the short end of the stick and only live an average of 55 years. While 55 is a long time, it's nothing compared to females who live 80-150 years.


Lake Sturgeon can be found in various lakes and rivers throughout the state, including Lake Michigan, Lake Huron, and the Detroit River. They have inhabited the Great Lakes for thousands of years. They are one of the oldest species on the planet.

In 2021, the U.S. Fish and Wildlife Service pulled a giant lake sturgeon out of the Detroit River. This sucker was massive as it was nearly 7 feet long and weighed more than 200 pounds. It was believed that she was over 100 years old and had been roaming the Detroit River around 1920 when Detroit became the 4th largest city in America.
