This enormous 4-meter (13-foot) sturgeon was seen in the Kennebec River, Maine, a reminder of the incredible giants that still roam our waters. Sturgeons, often called "living fossils," have existed for over 200 million years. The largest ever recorded was a Beluga sturgeon caught in the Volga estuary in 1827, measuring 7.2 meters (24 feet) and weighing over 1.5 tons (3,463 lbs). With their armored bodies and ancient lineage, these fish are a true testament to nature’s resilience.
