Elassoma Jordan , 1849, is a genus of freshwater fish, the only member of family Elassomatidae and suborder Elassomatoidei of order Perciformes. The type species is E. zonata, the banded pygmy sunfish . The Elassomatidae are known collectively as pygmy sunfishes, but are not true sunfishes, which are members of family Centrarchidae.
The pygmy sunfishes only grow to a maximum overall length of 3–4 cm (roughly 1.25–1.5 in). They occur mostly in temperate and subtropical swamps, marshes, and other shallow, slow-moving, and heavily-vegetated waters, across an area of the American South stretching from the Carolinas to Alabama and down into southern Florida. One species, the bluebarred pygmy sunfish (E. okatie) is considered Vulnerable.
The generic name Elassoma derives from the Greek ελάσσων (smaller) and σώμα (body), in reference to the fishes' diminuitive size compared to the true sunfishes.
