Study Estimates Great Lakes Lake Sturgeon May Live Up to 427 Years
A study analyzing 44 years of data from five Great Lakes populations estimates that female lake sturgeon may live up to 427 years, significantly longer than previous estimates of around 150 years. These freshwater fish, often called "living dinosaurs," are among the longest-lived vertebrates, comparable to Greenland sharks, which can live up to 512 years. Researchers tracked individual fish growth over time to derive these lifespan estimates, highlighting the species' remarkable longevity and ancient lineage.
