Three-toed AmphiumaAmphiuma tridactylum
Sometimes called the Congo Eel, the Three-toed Amphiuma is a slippery, snake-like, aquatic salamander of the Mississippi flood plain.
Reaching lengths of more than three feet, the Three-toed Amphiuma is among our largest salamanders. Adults are bi-colored, with a black, slate, or brownish back and a lighter gray belly. The four limbs are extremely thin and elongated and each foot has three toes. The tail is laterally compressed to aid in swimming and there are no external gills.
The Lesser Siren is also eel-like, but unlike the Three-toed Amphiuma, it lacks hind legs and has external gills.
Found in semi-permanent and permanent bodies of water such as bayous, ditches, and ponds that are muddy and mucky.
Earthworms, crayfish, fish, insects, mollusks, snakes, tadpoles, frogs, and smaller amphiumas are all prey items for this species.
Breeding takes place underwater in late winter or spring. A string of around 200 eggs is laid in a depression in the mud under a log or other debris. Females guard their egg masses for the duration of development, which takes approximately five months.
