Description

The banded sunfish is similar to the blackbanded sunfish and has a very compressed and deep body. Its sides are iridescent and dark colored. There are dark bands on its side and nuptial males and females will develop blue specks on their bodies. Its mouth is upturned and its pectoral and tail fins are rounded. It grows to an approximate length of 9.5 cm. [3]

Distribution

The banded sunfish is found in the Atlantic coastal drainages of North America from southern Maine south to central Florida and along the Gulf slope as far west as the Perdido River drainage in Alabama.[1]

Habitat

The banded sunfish is found in small ponds and backwaters of creeks to small and large rivers and boggy brooks over sand or mud in sluggish, acidic, heavily vegetated waters.[3]

Diet

The banded sunfish feeds upon aquatic insects, microcrustacean.[3]

Reproduction

Spawning occurs from April through July. They can spawn when they become one year old. The male will construct a sand or gravel nest where the eggs are laid but does guard the eggs as the eggs are buoyant and float way from the nest.[3]

Status

The banded sunfish is currently endangered in Pennsylvania, New York, New Jersey, New Hampshire, and Connecticut.[4] Globally, however, its population is stable and is listed as Least Concern on the IUCN Red List.[1]

Taxonomy and etymology

The banded sunfish was first formally described as Pomotis obesus in 1854 by the French ichthyologist Charles Frédéric Girard (1822-1895) with the type locality given as Framingham and in a branch of the Charles River, at Holliston, Massachusetts.[5] The generic name Enneacanthus means "nine-spined" while the specific name obesus means "fat".[6]
