Range and Identity
Fundulus sciadicus is native chiefly to the Missouri drainage, with a geographically separate occurrence in the Neosho system. That pattern should not be stretched into continuous occupancy of every intervening watershed. Exact drainage information matters when describing populations near the edges of its range.
Habitat and Behavior
Fish occur in vegetated springs and their outflows, along with quiet pools and backwaters. Sheltered water and plants are recurring features. A spring source and a downstream pool may provide connected habitat while differing substantially in flow, temperature and seasonal conditions.
Food and Life History
The compiled size summary reaches nine centimeters total length, while its narrative gives a smaller upper figure. Nine centimeters is retained as a qualified reference rather than a typical size. This is a nonannual killifish; no annual drying requirement or maximum weight is inferred.
Field Note
Note the vegetation and connection to spring water where visible. Those observations describe the occupied habitat more accurately than the surrounding grassland alone.
