Etymology: Aphredoderus:Greek, aphod = excrement + Greek, dere = throat, in reference to the unusual postion of the anus (Ref. 45335); sayanus:Named after the naturalist Thomas Say (Ref. 10294). Eponymy: Thomas Say (1787–1834) was a self-taught American naturalist whose primary interest was entomology. [...] (Ref. 128868), visit book page.
North America: Eastern and central United States. Previously, two subspecies were recognized by Boltz & Stauffer 1993 (Ref. 34807): Aphredoderus sayanus sayanus in Atlantic Coast drainages from New York to Georgia; and A. sayanus gibbosus in the Mississippi River, Great Lakes, and western Gulf Coast drainages, with intergrades in Gulf Coast and Atlantic Coast drainages between Mississippi and Georgia. 北美洲: 東方而中央的美國。 二個亞種被辨識特徵為 Boltz& Stauffer 1993:(參考文獻 34807) 到喬治亞州的在大西洋的海岸流域從紐約中的 Aphredoderus sayanus sayanus; 而且密西西比河，五大湖與西方的岸灣流域的 A. sayanus gibbosus, 與在密西西比與喬治亞州之間的岸灣與大西洋的海岸流域的中間等級。

成熟度: Lm? range ? - ? cm Max length : 14.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5723); common length : 10.4 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大年齡: 4 年 (Ref. 12193)
Adults usually occur over mud in swamps, vegetated sloughs, ponds, lakes, backwaters, and quiet pools of creeks and small to large rivers (Ref 5723, 10294). Nocturnal feeders. They feed on aquatic insects, small crustaceans, and occasional small fish including their own young (Ref. 10294). Eggs in nests are guarded by both parents (Ref. 205).
