A tiny snail believed to have lived only in Georgia has been declared extinct.
The snail was discovered in the 1970s and lived in a handful of creeks and streams near Lake Blackshear in southwest Georgia.
A senior aquatic biologist with the Georgia Department of Natural Resources, Jason Wisniewski, says the tan snail was a few millimeters long, "not much bigger than a few grains of salt."

The snail hadn't been documented since 2000. The species was part of a 2016 lawsuit against U.S. Fish and Wildlife intended to procure federal protections.
Wisniewski says snail's extinction could indicate larger issues in the environment.
