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); zebrinus: From the Latin word Fundus=bottom, the habitat; zebrinus=like a zebra (in reference to the vertical bars or stripes) (Ref. 79012). More on author: Jordan, Gilbert.
Environment / Climate / Range
Freshwater; brackish; benthopelagic; pH range: 7.0 - ?; non-migratory. Tropical; 20°C - 25°C (Ref. 2060); 46°N - 29°N
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 27139); common length : 6.9 cm TL male/unsexed; (Ref. 12193); max. reported age: 3 years (Ref. 12193)
North America: Mississippi River and Gulf Slope basins in the USA from northern central Montana to central Wyoming and south to Colorado River, Brazos River, Galveston Bay and Rio Grande drainages in Texas (Ref. 5723). Distinct from Fundulus kansae which is found in the drainages north of the Red River (Ref. 55961).
Inhabits shallow sandy runs, pools, and backwaters of headwaters, creeks and small to medium rivers. Tolerates extremely alkaline and saline streams, and often found where few other fishes can survive. Buries headfirst in sand and orients itself with only mouth and eyes are visible. This habit may protect the fish from intense sunlight or may help avoid predators, detect potential prey, or stream desiccation. 10 cm max TL (Ref. 5723). Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139).
