Centrarchus pomotis Baird, 1855 The mud sunfish (Acantharchus pomotis) is a freshwater ray-finned fish, a sunfish from the family Centrarchidae, which widely distributed in the fresh waters along the Atlantic coast of North America, ranging from New York to Alabama.

The mud sunfish was first formally described as Centrarchus pomotis by Spencer Fullerton Baird in 1855 with the type locality given as Cedar Swamp Creek, Beesley's Point, Cape May County, New Jersey and the Hackensack River, Rockland County, New York.

[6] It has a dark spot on the gill cover and the color of its body varies from brown on the back to yellowish tan on the flanks, while the juveniles are pale olive.

[2] The mud sunfish occurs along the eastern seaboard of the United States from southern New York south as far as northern Florida.

[6] The range of this species just extends into Alabama where they have been recorded in Beaver dam Creek in Washington County.

What has been discovered is that spawning appears to vary with latitude with gravid females being collected during the late spring and early summer in Delaware while further south, in North Carolina and Georgia spawning takes place during the early fall and late winter.

Their diet is made up largely of invertebrates including amphipods, decapods, and beetles with some smaller fishes and Odonata.

[7] Its range has also significantly reduced in New Jersey, particularly in the northern and central parts of the state but it remains reasonable common and widespread in the Pinelands.
