Etymology: Macrhybopsis: Greek, makros = great + Greek, ybos, -e, -on = rounded + Greek, opsis = appearance (Ref. 45335); boschungi: Named after the late Dr. Herbert T. Boschung, Emeritus Professor of Biology at the University of
Alabama, for his many contributions over the years to southeastern ichthyology in general and the state of Alabama in particular, including co-authorship of Fishes of Alabama (Boschung & Mayden 2004).

Morphology | Morphometrics
Occurs in larger, moderately clear to turbid rivers and the lowermost parts of their major tributaries below the Fall Line in the Mobile Bay basin. These areas have moderate to strong water current and bottom comprising of a combination of gravel, sand and silt. Inhabits sympatrically with Macrhybopsis etnieri (with no evidence of hybridization) over a 40-km section of middle Cahaba River in Fall Line area of Alabama (Ref. 116539).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00235 - 0.01070), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (18 of 100) .
