The mud sunfish (Acantharchus pomotis) is a sunfish from the family Centrarchidae that is widely distributed in the fresh waters along the Atlantic coast of North America, ranging from New York to Florida.
The mud sunfish prefers sluggish, weedy waters of 10″“22 Â°C (50″“72 Â°F), over muddy, detritus-strewn bottoms, and occurs in small lakes as well as riverine backwaters. The maximum recorded size of this species is 21 cm (8 in).
Te mud sunfish is currently the only species of genus Acantharchus Gill, 1864, but Baird had originally assigned it to Centrarchus. The mud sunfish is sometimes also known as the mud bass.
