Species of killifish grouped by geographic location

Killifish are found all over the world except for the Antarctic and Northern Europe. The greatest number of species are in Africa, while the greatest number of species in a single country are in North America. So common are killies in the United States of America that in some areas there "killifish" are synonymous with "bait" - in reference to Fundulus chrysotus.
