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); smithi: Named after a prominent vertebrate zoologist, Dr. Philip W. Smith (Ref. 10294).
Eponymy: Philip Wayne Smith (1921–1986) was a herpetologist and ichthyologist at the Illinois Natural History Survey (1953–1979). He is best known for his two monographs: The Amphibians and Reptiles of Illinois (1961) and The Fishes of Illinois (1979). (Ref. 128868), visit book page.

Inhabit rocky pools of headwaters, creeks and small rivers, and rocky margins of medium-sized rivers and impoundments (Ref. 5723); also found in streams (Ref. 10294).
