Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); boschungi: Named after an ichthyologist at the Univ. of Alabama, H. T. Boschung (Ref. 10294).

Maturity: L_m ? range ? - ? cm
Max length : 7.8 cm TL male/unsexed; (Ref. 5723); common length : 4.6 cm TL male/unsexed; (Ref. 12193)

Occur in gravel-bottomed pools, runs of creeks, small rivers (Ref. 5723) and streams (Ref. 10294); usually found in debris. Spawn in headwaters (Ref. 5723, 10294). Adults feed on aquatic isopods, amphipods (Hyalella), mayfly nymphs (Stenonema, Leptophlebia), midge larvae, and limpets (Ref. 10294). Eggs are found attached to the substrate unguarded (Ref. 7043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
