Sturgeon, known as “living fossils,” have been around for over 200 million years. These giant fish have kept their ancient look and have barely changed over time. Found in rivers across North America, Europe, and Asia, sturgeons are known for their large size, long lifespan, and slow reproduction. While they face threats like overfishing and habitat loss today, their ability to survive for so long shows just how successful they’ve been in evolving.
