Ecology of Hybognathus hankinsoni
 
Main Ref. Scott, W.B. and E.J. Crossman, 1973
Remarks Occurs in cool pools of sluggish, clear creeks and small rivers, usually over sand or gravel; more abundant in cool acid waters of silt-bottomed bog ponds (Ref. 1998). Probably feeds on phytoplankton and other algae, zooplankton, and aquatic insects (Ref. 1998). Probably preyed upon by brook trout, kingfishers, and mergansers (Ref. 1998).
