About Black Darter
Etheostoma duryi, the black darter, is a species of darter endemic to the eastern United States, where it occurs in the drainage of the Tennessee River in the states of Tennessee, Georgia, and Alabama. It is an inhabitant of rocky pools in streams and smaller rivers and their adjacent riffles. This species can reach a length of 7.2 cm (2.8 in), though most only reach about 5 cm (2.0 in). The specific epithet honors Charles Dury (1847–1931), who collected the original type specimens.
Diet and feeding
The FishTraits compilation records these diet categories for this species: invertebrates or larval fish. These are broad categories, not a claim that every individual consumes every example in a category.
Reported feeding positions include bottom feeding. The compilation combines published observations; diets can vary with age, locality, and available food.
Habitat preferences
Reported habitat associations include medium to large rivers, streams and small rivers, creeks.
The source records associations with sand, gravel, cobble, boulders. An association indicates reported use, rather than an exclusive requirement.
Reproduction and parental care
The compilation reports a representative maturity age of 1 years. Its maturity field summarizes mean, median, or modal estimates, usually for females; male estimates can be used when female data are unavailable. It is not a fixed age at which every fish first breeds.
Recorded spawning months are Mar, Apr, May for the source’s reporting region (MS). This is a regional calendar, not a range-wide schedule.
The reproductive-guild classification includes guarding eggs or young at a spawning substrate or nest.
Size and recorded longevity
FishTraits reports a maximum total length of 7.2 centimetres. Some entries use an estimated asymptotic length; this value should not be treated as a certified record catch.
Recorded longevity in the compilation is 3 years. Wild observations were preferred, but captive records were accepted where wild records were unavailable, and unspecified records were assumed wild. The value is not a guaranteed wild lifespan or an aquarium life expectancy.
Range
Where it lives
A blank area on the dot layer usually means nobody sampled there, not that the fish is absent. Turn on “every survey site” to see where the survey looked.
Share of records by state
The USGS stream survey caught it at 90 of its sites, in 2 states. That survey and the GBIF records are two different counts of two different things, so the site keeps them apart.
