They can be found in the states of Tennessee, Kentucky, Mississippi, Missouri, and Texas. They are one of the three species that belong to the Amphiuma genus. The other two are the one-toed amphiuma (Amphiuma pholeter) and the two-toed amphiuma (Amphiuma means). The average body length of adult Amphiuma tridactylum is about 18-30 in (45.7-76 cm). They have long, cylindrical, eel-like bodies. They are usually dark brown, gray, or black but their underbellies are paler than their backs. The underside of their neck is darker. They have four vestigial legs that have three toes. The young have gills, while adults use their lungs for respiration. They mature at an age of three-four years. They also have small, lidless eyes. Males are usually a little larger and heavier than females. These large salamanders prey on crayfish, fish, tadpoles, frogs, insects, and smaller amphibians and reptiles. Amphiumas are also called the Congo eel. They are often found in lakes, burrows, ponds, and swamps. Female three-toed amphiumas can lay about 50-200 eggs in a clutch.

How do they reproduce?

Amphiuma tridactylum is a polygynandrous species, meaning both males and females of the species have multiple partners. Their breeding season occurs from January to April. Males touch females to show interest in mating, if the females feel the same way, they also return the gesture. During aquatic mating, the male swims in circles and flaps their tail on the surface of the water, and the female also swims below them to make their cloaca touch. There have been instances of females competing for mates but males do not show any such behavior. Heavy rain stimulates their breeding process. Internal fertilization of eggs is also a feature of these amphibians. Females can store the sperm inside their bodies for up to seven months and show delayed fertilization. Females mate every two years while males mate annually. Females can lay up to 200 eggs in one clutch. They lay eggs in burrows close to the water in wet, soft mud, on fallen branches, and also under logs. The eggs are opaque and have a jelly-like consistency.
