Everglades Pygmy Sunfish (Elassoma evergladei)

The Everglades Pygmy Sunfish occurs in Atlantic and Gulf coastal drainages from North Carolina to Alabama. As its common name implies, the Everglades Pygmy Sunfish has a maximum size of just over one inch and has a lifespan of one year. While this species is found outside of the Everglades, it prefers vegetated habitats found in sloughs and backwaters.

Spring Pygmy Sunfish (Elassoma alabamae)

This federally threatened species was historically known from three sites in the middle Tennessee River Drainage, but is now restricted to a single spring-fed creek system. As its common name implies, the Spring Pygmy Sunfish requires cool groundwater and has a maximum size of just over one inch. This species has a lifespan of only one year and thus is vulnerable to random changes in its environment

Pygmy Sculpin (Cottus paulus)

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.
