Northern Dwarf Siren is the smallest member among the family Sirenidae, at only 4.0–9.9 inch (10–25 cm). Like other sirens, it is aquatic, breathes through gills the entire life and lacks hind legs. It has slender, eel-like body with light stripes on its side compared to the brown or light-grey dorsal part. The siren has only one gill slit, a finned tail, three toes on each of the front feet.
The species dwells at pond bottoms and among roots of floating plants. It can be found in shallow ditches, cypress swamps, and weed-choked ponds on the wetlands of South Carolina, Georgia, and Florida. The siren feeds on small invertebrates.
Northern Dwarf Sirens gather in large numbers at ponds in Spring to breed. They fertilize externally and each of them can lay up to 61 eggs in a breeding season. Each egg is laid singly on roots of aquatic plants. It takes a month for larvae to hatch and 4 years for them to reach sexual maturity.
