North America: found only in the lower Caney Fork system and nearby tributaries of Cumberland River in central Tennessee, USA.

Biology     Glossary (e.g. epibenthic)

Inhabit rocky pools and nearby riffles of headwaters and creeks (Ref. 5723); also found in streams (Ref. 10294). Often found in very shallow water less than 4 m deep (Ref. 5723). Juveniles feed on midge larvae and microcrustaceans; adults on midge larvae, other immature aquatic insects (mayflies, caddisflies, stoneflies), isopods and amphipods (Ref. 10294). Eggs are found clustered on underside of stone and guarded by males (Ref. 7043).

Eggs are found clustered on underside of stone (Ref. 7043). Males guard the eggs (Ref. 7043).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (tmax=2).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
