Rare snail slowly crawls back from near extinction along northwest Georgia river

In a stretch of north Georgia river lives a snail that has come back from the dead.

The interrupted rocksnail, a slimy little orange guy, was once thought to be extinct, but in 1997, the United States Geological Survey found a single snail.

They called Paul Johnson, program supervisor at the Alabama Aquatic Biodiversity Center, who was working with the Tennessee Aquarium Research Institute in Georgia at the time, and he set out to the Oostanaula River to try to find more of the snails.
