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); crossopterum: From the words crosso, meaning fringed; and pteron, fin (referring to the fringed soft dorsal fin of nuptial males) (Ref. 10294).
Environment / Climate / Range

North America: in lower Cumberland River drainage in Kentucky and Tennessee, USA; in the middle Duck River system in Tennessee, and Shoal Creek system in Tennessee and Alabama; and in Reelfoot Lakes tributaries in Tennessee.

Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 5723)
Inhabits rocky pools and adjacent riffles of headwaters, creeks and small rivers (Ref. 5723); also found in streams (Ref. 10294). Feeds on aquatic insect immatures, including midge and caddisfly larvae and mayfly nymphs, and crustaceans, such as isopods, amphipods, and small crayfishes (Ref. 10294).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00205 - 0.01282), b=3.14 (2.92 - 3.36), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (22 of 100) .
