Everglades Pygmy Sunfish (Elassoma evergladei)

The Everglades Pygmy Sunfish occurs in Gulf and Atlantic coast drainages from Alabama to North Carolina. As the common name implies, Everglades Pygmy Sunfish have a maximum size of just over one inch and have a lifespan of one year. They are found in vegetated habitats in sloughs and backwaters that are typical of the Everglades.

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 the common name implies, Spring Pygmy Sunfish require cool groundwater and have a maximum size of just over one inch. They have a lifespan of only one year and are vulnerable to random changes in the 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 groundwater pollution or other local impacts to their extremely small range. As the 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.
