Etymology: Opsopoeodus: Greek, ops, = face, appearance + Greek, pous = foot + Greek, odous = teeth; emiliae: opsopoeodus, teeth for dainty feeding (Greek); and emiliae, named after Mrs. Emily Hay (wife of the author of the species, Dr. O. P. Hay) (Ref. 10294).
Eponymy: Mrs Mary Emily ‘Mollie’ Hay née Howsman (1849–1931) was the author’s wife. [...] (Ref. 128868), visit book page.

North America: Edisto River drainage in South Carolina to southern Florida and across Gulf Slope to Nueces River drainage in Texas, USA; north in Mississippi River and Great Lakes basins to southeastern Kansas, southeastern Minnesota, USA, and southern Ontario, Canada. The subspecies were previously recognized: Opsopoeodus emiliae peninsularis in peninsular Florida and Opsopoeodus emiliae emiliae in rest of range except where intergrades occur (southern Georgia and northeastern Florida west to Ochlockonee River).

Maturity: L_m ? range ? - ? cm
Max length : 6.6 cm TL male/unsexed; (Ref. 10294)

Inhabits clear to turbid vegetated lakes, swamps, oxbows, sluggish streams of all sizes (Ref. 86798). Feeds on insect larvae, filamentous algae and microcrustacea (Ref. 10294). Spawning occurs underneath flat rocks, in cavities; nest spawner (Ref. 79012).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00242 - 0.01036), b=3.11 (2.92 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.35 se; based on food items.

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).
