[4], There are two subspecies, the eastern banded killifish Fundulus diaphanus diaphanus and the western banded killifish Fundulus diaphanus menona. Due to biogeographical isolation and limitation of potential for range expansion, banded killifish species were assigned a status of special concern by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Jenkins, and J.R. Stauffer, Jr. 1986. [18] An individual of different color might present as a contrast.
