🐟 NEW: Recent long-term tracking #research indicates that lake #sturgeon in the #GreatLakes may reach ages exceeding 400 years. By using capture-mark-recapture #data across decades, fishery biologists updated growth rate models for these #ancient cartilaginous #fish, showing lifespans nearly three times longer than previous estimates and rivaling some of the longest-living #vertebrates on Earth. 👉 https://www.smithsonianmag.com/science-nature/some-fish-in-the-great-lakes-might-be-more-than-400-years-old-a-study-suggests-outliving-around-15-generations-of-humans-180989500/ #lakesturgeon #freshwater #biology #science #ecology #nature #animals #wildlife #conservation #history
