Elassomatidae
''Elassoma'' is a genus of freshwater fish, the only member of subfamily Elassomatinae of the sunfish family Centrarchidae in the order Perciformes. It is sometimes classified as a separate family, the Elassomatidae, in a monotypic suborder, Elassomatoidei, in Perciformes. The type species is ''E. zonatum,'' the banded pygmy sunfish. The Elassomatinae are known collectively as pygmy sunfishes, but are considered by some authorities not to be true sunfishes, which are members of family Centrarchidae. Some researchers believe they are related to sticklebacks and pipefishes (order Syngnathiformes) rather than Perciformes, though genetic research strongly implies a close relationship with the centrarchids. Currently the Integrated Taxonomic Information System classifies them in the family Elassomatidae rather than Centrarchidae. The pygmy sunfishes grow to a maximum overall length of . They occur mostly in temperate and subtropical swamps, marshes, and other shallow, slow-moving, ...

Banded Pygmy Sunfish
The banded pygmy sunfish, ''Elassoma zonatum'', is a species of pygmy sunfish endemic to the United States, where it is found from Indiana and Illinois to Texas to the Atlantic coast. It prefers densely vegetated bodies of slow-moving water. This species can reach in total length, though most do not exceed . The banded pygmy sunfish are capable of retaining their juvenile characteristics while they are sexually mature; that is to say that they are neotenous. It was originally thought that the banded pygmy sunfish belonged to the cichlid family. However, researchers Hay, Jordan, and Gilbert thought that the banded pygmy sunfish was actually an intermediate species of fish between the pirate perch and the centrarchid family of fishes. Therefore, the banded pygmy sunfish was placed into its own family, Elassomatidae. In the 5th edition of '' Fishes of the World'', though, this is treated as a subfamily of the sunfish family Centrarchidae. Etymology The banded pygmy sunfishes ...

Centrarchidae
Centrarchidae, better known as sunfishes, is a family of freshwater ray-finned fish belonging to the order Perciformes (formerly belonging to the deprecated order Centrarchiformes), native only to North America. There are eight universally included genera within the centrarchid family: ''Lepomis'' (true sunfishes), ''Micropterus'' (black basses), ''Pomoxis'' (crappies), ''Enneacanthus'' (banded sunfishes), ''Centrarchus'' (type genus, consisting solely of the flier ''C. macropterus''), ''Archoplites'' ( Sacramento perch), ''Ambloplites'' (rock basses), and ''Acantharchus'' (mud sunfish). A genetic study in 2012 suggests that the highly distinct pygmy sunfishes of the genus ''Elassoma'' are also centarchids. The centrarchid family comprises 38 identified species, 34 of which are extant. It includes many popular game fishes familiar to North American anglers, such as the rock bass, largemouth bass, bluegill, pumpkinseed, green sunfish and crappies. Most sunfish are highly valu ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ...

Mississippi River Valley
The Mississippi embayment is a physiographic feature in the south-central United States, part of the Mississippi Alluvial Plain. It is essentially a northward continuation of the fluvial sediments of the Mississippi River Delta to its confluence with the Ohio River at Cairo, Illinois. The current sedimentary area was formed in the Cretaceous and early Cenozoic by the filling with sediment of a pre-existing basin. An explanation for the embayment's formation was put forward by Van Arsdale and Cox in 2007: movement of the earth's crust brought this region over a volcanic " hotspot" in the Earth's mantle causing an upthrust of magma which formed the Appalachian-Ouachita range. Subsequent erosion caused a deep trough that was flooded by the Gulf of Mexico and eventually filled with sediment from the Mississippi River. Geography The embayment is a topographically low-lying basin that is filled with Cretaceous to recent sediments. The northern end of the embayment appears as a ...

Subtropical
The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Geographical zone#Temperate zones, temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical climate, humid subtropical (Köppen climate classification, Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example list of regions of China, Southeast China and the Southeastern United States, and Mediterranean climate, dry summer or Mediterranean climate (Köppen climate classification, Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the c ...
