Found in a large stream about 10 meters wide, the water mostly shallow, less than 1 meter deep; bottom of mixed rock, sand, and gravel, providing riffles; slightly brownish and turbid. Radiographed specimens reveal considerable amounts of small shells in the guts and intestines. The stout lower pharyngeal bone consistent with a snail diet (Ref. 51414).
