Carolina Pygmy Sunfish
This tiny olive fish is restricted to vegetated blackwater habitats in South Carolina’s Edisto and nearby coastal drainages.
Artwork inspired by Boyd Saunders
Carolina Pygmy Sunfish live among dense submerged plants, roots, and leaf litter where slow acidic water filters through Coastal Plain wetlands. Males darken dramatically during courtship, flashing iridescent blue-green spots while remaining scarcely longer than a fingertip.
Drainage, groundwater withdrawal, sediment, herbicides, and removal of aquatic vegetation can erase whole local populations. Its habitat is fragile and exact sites should not become collecting destinations.
