Fundulidae (Topminnows and killifishes)
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); chrysotus: chrysotus meaning golden (Ref. 10294).
More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic; non-migratory. Subtropical; 18°C - 25°C (Ref. 2060); 36°N - 26°N
North America: USA from Santee River drainage in South Carolina to Trinity River drainage in Texas; Former Mississippi Embayment north to Kentucky and Missouri. East of Mississippi River mostly restricted to lower Coastal Plain.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm TL male/unsexed; (Ref. 27139); common length : 4.0 cm TL male/unsexed; (Ref. 12193)
Adults occur in swamps, sloughs, vegetated pools, and backwaters of sluggish creeks and small to medium rivers (Ref. 5723, 10294). Feed primarily on insects (Ref. 10294). Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139).

Trophic level (Ref.
69278): 3.2 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref.
