Three-Lined Salamander
Eurycea guttolineata · also called three-lined salamanders
Through a dense mat of wet leaf litter in a southeastern floodplain forest, a three-lined salamander moves with surprising speed, its tail alone accounting for well over half its total length as it wriggles between obstacles most shorter-tailed salamanders would need to navigate around.
Overview
The three-lined salamander, Eurycea guttolineata, is a long-tailed salamander native to wetland and forest habitat across a broad range of the southeastern United States. Its exaggerated tail length and bold triple-striped pattern make it one of the more physically distinctive and visually striped members of its genus.
A tail built for speed through clutter
Most of a three-lined salamander’s total length isn’t body at all, it’s tail, an unusual proportion that turns dense leaf litter and tangled vegetation into terrain this particular salamander can move through considerably faster than its shorter-tailed relatives.
Status
Least Concern — widespread and common across suitable wetland and forest habitat throughout the southeastern United States.
Three-Lined Salamander: common questions
Why does the three-lined salamander have such a long tail?
A three-lined salamander has a notably long tail that can make up well over half of its total body length, an exaggerated proportion thought to aid rapid, agile movement through dense vegetation and leaf litter, letting the salamander manoeuvre quickly through cluttered ground cover.
How is the three-lined salamander different from the long-tailed salamander?
Both species share notably long tails and overlapping range in parts of the southeastern United States, but the three-lined salamander is distinguished mainly by its three distinct dark back stripes, while the long-tailed salamander typically shows a more herringbone-like pattern of dark markings along the tail specifically.
Where does the three-lined salamander breed?
A three-lined salamander begins life as an aquatic larva in streams, ditches, and pools before transforming into a more terrestrial adult, though even as an adult it tends to stay within moist floodplain forest or wet meadow habitat rather than ranging far from water.
Where does the three-lined salamander live?
The three-lined salamander is native to wetland and forest habitat across a broad range of the southeastern United States, favouring floodplain forest, wet meadows, and stream margins.
