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).
Environment: milieu / climate zone / distribuzione batimetrica / distribution range
Ecologia
; acqua dolce benthopelagico; non migratori. Subtropical
North America: endemic to Bermuda. Fundulus relictus is believed to be a descendant of the Fundulus heteroclitus - F. grandis species group originating from populations on the east coast of North America (Ref. 59062). It is presently believed that none of the killifish ponds in Bermuda contain mixed populations of Fundulus bermudae and F. relictus.

Endangered and endemic species found in Bermuda with highly fragmented populations and a very limited range. Found only in a limited number of isolated brackish water ponds and appear to form loose schools consisting of equally sized individuals (Ref. 59051). This species is regarded as omnivorous opportunistic feeder (Ref. The main predators to Bermuda’s endemic Fundulus populations include a variety of birds (mostly herons), and fishes (eastern mosquito fish Gambusia holbrooki, gray snapper Lutjanus griseus, American eel Anguilla rostrata). Additionally, it is believed that the introduced and invasive red-eared terrapin Trachemys scripta elegans is a significant predator in a limited number of ponds (Ref. 59051). Non-annual killifish. Is difficult to maintain in aquarium (Ref. 27139).
