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); striatulum: striatulum refers to the striated appearance due to faint dark horizontal lines along the sides (Ref. 10294).

Maturity: Lm ?  range ? - ? cm
Max length : 5.6 cm TL male/unsexed; (Ref. 5723); common length : 3.9 cm TL male/unsexed; (Ref. 12193); max. reported age: 2.00 years (Ref. 12193)
Inhabit rocky pools of headwaters and creeks (Ref. 5723, 10294). Feed on midge larvae and microcrustaceans (Ref. 10294). Eggs are found clustered on underside of stone and guarded by males (Ref. 7043).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00301 - 0.01516), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (tmax=2).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
