Fundulus
''Fundulus'' is a genus of ray-finned fishes in the Taxonomic rank, superfamily Funduloidea, family (biology), family Fundulidae (of which it is the type genus). It belongs to the order (biology), order of toothcarps (Cyprinodontiformes), and therein the large suborder Cyprinodontoidei. Most of its closest living relatives are egg-laying, with the notable exception of the splitfin livebearers (Goodeidae). They are usually smallish; most species reaching a length of at most 4 in (10 cm) when fully grown. However, a few larger species exist, with the giant killifish (''Fundulus grandissimus, F. grandissimus'') and the northern studfish (''Fundulus catenatus, F. catenatus'') growing to twice the genus' average size. Many of the 40-odd species are commonly known by the highly ambiguous name "killifish" (the general term for egg-laying toothcarps), or the somewhat less ambiguous "topminnow" (a catch-all term for Fundulidae). "Studfish" is a quite unequivocal vernacular name appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fundulus Heteroclitus
The mummichog (''Fundulus heteroclitus'') is a small killifish found along the Atlantic coast of the United States and Canada. Also known as Atlantic killifish, mummies, gudgeons, and mud minnows, these fish inhabit brackish and coastal waters including estuaries and salt marshes. The species is noted for its hardiness and ability to tolerate highly variable salinity, temperature fluctuations from , very low oxygen levels (down to 1 mg/L), and heavily polluted ecosystems. As a result, the mummichog is a popular research subject in embryological, physiological, and toxicological studies. It is also the first fish ever sent to space, aboard Skylab in 1973. Taxonomy The genus name ''Fundulus'' comes from ', meaning bottom, from the fish's habit of swimming near muddy bottoms. The species name ''heteroclitus'' means irregular or unusual. The type specimen was first described by Carl Linnaeus in 1766, from near Charleston, South Carolina. Other scientific names now considered syn ...

Fundulus Nottii
''Fundulus nottii'', the bayou topminnow or southern starhead topminnow, is a fish of the family Fundulidae found in the southeastern United States. Description It is a small topminnow with a sub-ocular teardrop, a terminal to superior mouth, and a rounded caudal fin. The top of the head is flat, with the large scale (located just anterior to a line between the eyes) overlapped by the pair of scales just behind it.
