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); caeruleum: caeruleum meaning blue (Ref. 10294).

Adults inhabit fast gravel and rubble riffles of creeks and small to medium rivers (Ref. 5723, 10294); also found in streams (Ref. 10294). Feed on midge larvae, hydropsychid and hydroptilid caddisfly larvae, mayfly nymphs, and fish eggs (Ref. 10294). Distinct pairing during breeding (Ref. 36980). Eggs are found buried in the substrate (Ref. 7043).

Estimates based on models
Índice de diversidade filogenética (Ref.

50 = 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.

Nível Trófico (Ref.
69278): 3.3 ±0.46 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
