Virginia Wildlife Action Plan Rating Tier III - High Conservation Need - Extinction or extirpation is possible. Populations of these species are in decline or have declined to low levels or are in a restricted range. Management action is needed to stabilize or increase populations.

PHYSICAL DESCRIPTION: This species averages 8 5/8 inches in length, with extremes of 5 9/32 inches and 13 5/8 inches recorded. The body is long, slender and eel-like. The head is long and widens just above the gills. The eyes are small and without lids. The mouth is small, crescentic, subterminal, and slightly overhung by the upper jaw. Nostrils are small and slit-like and placed at the ventrolateral angles of the snout. There are 31-34 costal grooves. The tail is broadly oval in cross section at the base, becoming more strongly compressed toward the tip. The dorsal tail fin arises as a low ridge above the vent, but immediately thins and continues to the tip. Only the forelegs are present. There are 4 toes on each front foot. The color varies from deep brown to olive-green. Many rounded black spots are scattered over the back and sides of the head, trunk, and tail. The ventral side is darker than the dorsal. Reproduction: This species usually inhabits still water in cypress or pine woods. It is also found in ditches, ponds, streams or reservoirs where aquatic vegetation, debris or bottom mud and muck allow it to hide during the day. In places where siren lacertina is also present it is less likely to inhabit rivers and streams.
