(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).
Environment / Climate / Range
Marine; freshwater; brackish; benthopelagic; non-migratory. Temperate; 10°C - 24°C (Ref. 12468); 52°N - 28°N, 82°W - 57°W
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 4 - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 27139); common length : 8.9 cm TL male/unsexed; (Ref. 12193)
Western Atlantic: Canada (Ref. 5951) to Sandy Hook, New Jersey to northeastern Florida, and in lower Chesapeake and Delaware bays (Ref. 35624). Introduced to southern Portugal and southern Spain (Ref. 59043).
A resident intertidal species with homing behavior (Ref. 32612). Mainly found in saltwater marshes and in tidal creeks. May leave tide pools if aquatic conditions become inhospitable (Ref. 31184). Enters fresh water to limited extent (Ref. 7251). Not a seasonal killifish. Breathes air when out of water (Ref. 31184). Difficult to maintain in aquariums (Ref. 27139). Its introduction has caused the decline of native species and near extinction of Aphanius baeticus in southwestern Spain (Ref. 59043).
