Pygmy Sculpin (Cottus paulus)

Description: 

The Pygmy Sculpin is a federally threatened species that is restricted to a single spring in east-central Alabama. The primary threat to this species is their narrow distribution and groundwater pollution. As its common name implies, the Pygmy Sculpin is smaller than other members of its family and does not reach two inches in length. Though their range is extremely restricted, they are abundant where they occur.
