Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > 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).

Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 5723)

Biology     Glossary (e.g. epibenthic)

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).

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):  3.2   ±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).
