Gilt Darter vs Tangerine Darter
A gilt darter and a tangerine darter are both larger-bodied members of their genus requiring fast, clean riffle habitat, yet one has been pushed into scattered fragments of its former range while the other remains widespread and secure across the southern Appalachians.
| Gilt Darter | Tangerine Darter | |
|---|---|---|
| Scientific name | Percina evides | Percina aurantiaca |
| Range status | Fragmented, lost from much of its range | Widespread and stable |
| Main historical threat | Dam construction, sedimentation | None major |
| Breeding colouration | Vivid golden-orange sides | Vivid orange lower body and fins |
| Relative size | Small to moderate | Among the largest darters in North America |
| Range | Scattered eastern and central US rivers | Southern Appalachians |
| Habitat | Fast, clean rocky riffles | Clean mountain streams and rivers |
| Conservation status | Vulnerable | Least Concern |
Gilt Darter vs Tangerine Darter: common questions
Why has the gilt darter declined while the tangerine darter has not?
The gilt darter has been affected significantly by dam construction, sedimentation, and pollution across much of its historical range, while the tangerine darter's core southern Appalachian range has not experienced the same scale of habitat degradation, allowing it to remain widespread and stable by comparison.
Which of these two darters is bigger?
The tangerine darter is considerably bigger, ranking among the largest darter species found anywhere in North America, while the gilt darter is a more modestly sized, though still larger than average, member of its own genus.
Do both darters flash a similar colour when breeding?
Both show a striking orange-toned breeding display, with a male gilt darter developing golden-orange colouration along the sides and a male tangerine darter developing vivid orange along the lower body and fins, though the two species belong to different genera and are not especially closely related despite the colour similarity.
