SCIENTIFIC NAME: Siren intermedia spp.
OTHER NAMES: Eastern lesser siren, western lesser siren
DESCRIPTION: This small eel-like salamander ranges from 7 to 19 inches in length. They are usually some form of gray to bluish black, and have two small forelegs tucked behind external gills. Four toes are found on each foreleg. Lighter specimens often have small dark spots along the head and dorsum. Juveniles have a red band along the snout and side of head.
DISTRIBUTION: From North Carolina south along the coastal plain into east Texas, northward up the Mississippi River Valley into Illinois and Indiana. In Alabama, south of the Fall Line Hills region. Both subspecies intergrade along west central Alabama.
HABITAT: This small aquatic salamander prefers swamps and shallow wetlands with abundant vegetation.
FEEDING HABITS: Lesser sirens rely heavily on aquatic arthropods and worms. Small amounts of vegetation have been found in the digestive tracts of some individuals.
LIFE HISTORY AND ECOLOGY: Little is known about the breeding habits of this small salamander. Few accounts exist, but suggest they breed in late winter and early spring. They have the ability to burrow into the mud during times of drought, and excrete a substance that encapsulates their entire body, except the nose and mouth. Upon the arrival of rain, they will resume normal activity.
