Fundulidae is the family oftopminnows and North Americankillifishes.[2]
The 46 species are native toNorth America as far south asYucatan, and to the islands ofBermuda andCuba, occurring in both freshwater and marine environments.
Most members of the family are small. While the giant killifish (Fundulus grandissimus) andnorthern studfish (Fundulus catenatus) can reach 20 cm (7.9 in) in length, most species are under 10 cm in length.
The distinguishing characteristic of the family is themaxillary bone, which is twisted instead of being straight.[3]
While many species of the Fundulidae are listed as not threatened, there are some that are listed as endangered because of their environment. Many common species of the Fundulidae live in North America such as the United States and Mexico. They live in different ecosystem such as costal marshes, lagoons, rivers, streams with high elevations with clear water, and muddy conditions at lower elevation. They are able to adapt to different conditions which is increasing their survival rate.[4][5]
