Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); bison: The specific epithet bison refers to the enlarged nuchal hump present on large breeding males w/c is reminiscent of the body shape of the North American bison..
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate
North America: Occurs in tributaries of the lower Duck and lower Tennessee Rivers.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
(total): 9 - 10;
soft rays: 7 - 8. Differs from all members of the complex in having in the breeding male the horizontal lines restricted to a series of long dark dashes, and upper sides with a zone of light tan extending the length of the body. It differs from all other species by modally having 8 anal rays and 6 scales below the lateral line (Ref. 27671).
