Tangerine Darter
Percina aurantiaca · also called tangerine darters
Looking down from a footbridge over a clear southern Appalachian river, a hiker spots a flash of vivid orange moving along the bottom, a breeding male tangerine darter large enough and bright enough to be seen clearly from a height most other darters could never be noticed from.
Overview
The tangerine darter, Percina aurantiaca, is one of the largest darter species in North America, native to clean mountain streams and rivers across the southern Appalachian region. Its unusually large size and vivid orange breeding display make it one of the more visually striking and physically impressive members of a typically small-bodied group of fish.
A darter big and bright enough to spot from above
While most darters require a close, careful look to appreciate, the tangerine darter’s combination of size and vivid colour makes it one of the few species in its group that can genuinely be admired from a distance, given clear enough water.
Status
Least Concern — widespread and stable across suitable clean mountain stream and river habitat throughout the southern Appalachian region.
Tangerine Darter: common questions
How big can a tangerine darter get?
The tangerine darter ranks among the largest darter species found in North America, considerably bigger than many of its smaller darter relatives, making it one of the more physically impressive members of this typically small-bodied group of fish.
Why is the tangerine darter's colour visible from above the water?
A breeding male tangerine darter develops vivid orange colouration along its lower body and fins, and because the species favours clean, clear mountain streams with excellent water visibility, this bright colouration can often be spotted by an observer looking down from a stream bank or bridge.
Does the tangerine darter live in the same habitat as smaller darters?
Broadly similar habitat, though the tangerine darter tends to favour somewhat deeper riffles and pools than many smaller darter species, generally avoiding the shallowest, fastest riffle margins that some of its smaller relatives prefer.
Where does the tangerine darter live?
The tangerine darter is native to clean mountain streams and rivers across the southern Appalachian region of Tennessee, North Carolina, Virginia, and Georgia, requiring consistently clear, well-oxygenated water.
