North America: Former Mississippi Embayment and Gulf Slope drainages from Kentucky and Missouri to Louisiana, and from Escambia River in Alabama and Florida to Neches River in Texas in the USA. In Red and Arkansas drainages west to Oklahoma and Texas; in Wabash River drainage and Green River system in USA.

Biology     Glossary (e.g. epibenthic)

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00503 - 0.03006), b=3.07 (2.85 - 3.29), based on LWR estimates for this Subfamily-BS (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 (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
Price category (Ref. 80766):   Unknown.
