Scientists have found evidence that the state's namesake sturgeon species, which many feared had slipped into extinction, persists in multiple locations in the Alabama River.

Scientists have not laid hands on an Alabama sturgeon since 2007, when state biologists captured a single fish.

In Endangered Species Act documents from 2010, the U.S. Fish & Wildlife Service wrote, "with only three documented occurrences in the last ten years, the Alabama sturgeon is undoubtedly one of the rarest freshwater fishes on the planet."

But Alexis Janosik, an assistant professor at the University of West Florida, and Steve Rider, a biologist with the Alabama Department of Conservation and Natural Resources, detected the fish's DNA in multiple water samples collected from the Alabama River in 2014 and 2015.
