Etymology: Fundulus: Latin, fundus = bottom; a peculiar name for a topminnow, coined for a bottom species of Atlantic coast being "the abode of the fundulus mudfish" (Ref. 45335); kansae: From the Latin word Fundus=bottom, the habitat; kansae in reference to the type locality (Ref. 79012) More on author: Garman.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; non-migratory; depth range - m (Ref. ), usually - m (Ref. ). Temperate; 20°C - 25°C
North America: U.S.A., in drainages to the north of the Red River of Texas and the Texas-Oklahoma border. Distinct from F. zebrinus based on molecular data and which occurs in the Red River and drainages farther south.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00294 - 0.01786), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.2 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.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
