Cumberland Darter
This federally endangered darter survives in a limited set of clear headwater streams in Kentucky and Tennessee, making connected riffles and clean gravel critical.

The Cumberland darter lives close to the bottom in shallow headwater streams, using gravel and cobble where current delivers oxygen and aquatic insects. Culverts, sediment, mining effects, and drought can fragment a population that already occupies only a small part of the upper Cumberland system.
Observation should be passive and opportunistic from a public bank. Several darters share similar patterns; without expert examination, habitat and behavior are more reliable learning targets than a confident species label based on a distant photograph.

Good to know
Precise endangered-species locations should remain protected. Public education should emphasize watershed condition, road-crossing design, and sediment control instead of promising a sighting.
