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); smithi: Named after a prominent vertebrate zoologist, Dr. Philip W. Smith (Ref. 10294).

Environment: milieu / climate zone / depth range / distribution range Ecology

North America: occurs only in the lower Cumberland (below Caney Fork) and lower Tennessee River (in lower Duck River and downstream) drainages in Kentucky and Tennessee, USA.

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 6.2 cm TL male/unsexed; (Ref. 5723); common length : 4.1 cm TL male/unsexed; (Ref. 12193); max. reported age: 2.00 years (Ref. 12193)

Inhabit rocky pools of headwaters, creeks and small rivers, and rocky margins of medium-sized rivers and impoundments (Ref. 5723); also found in streams (Ref. 10294). Adults feed on midge, mayfly, and immature caddisfly, with copepods and other 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): 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 (tmax=2; Fec=17-69).

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