Actinopteri (ray-finned fishes) > Perciformes/Percoidei
(Perchs) > Percidae
(Perches) > Etheostomatinae
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); chlorosomum: From the words chloro, meaning green; and somum, body (Ref. 10294). From the Greek etheo=to strain, and stoma=mouth; chlorosoma (Greek)=greenish-yellow (Ref. 79012).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical; 44°N - 29°N
North America: Mississippi River basin from southern Minnesota to Louisiana, USA and Gulf Slope from Mobile Bay drainage in Alabama to San Antonio River drainages in Texas in the USA. Formerly in Lake Michigan drainage in Illinois, USA.

Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 5723)
Inhabit muddy (sometimes sandy) pools and backwaters of creeks and small to medium rivers, weedy lakes and ponds, swamps (Ref. 5723) and streams (Ref. 10294). Adults feed on hydropsychid caddisfly, dytiscid beetle, and midge larvae (Ref. 10294). Eggs are found attached to the substrate unguarded (Ref. 7043).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00232 - 0.01243), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this Subfamily-BS (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 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
