Ecology of Ichthyomyzon fossor
 
Main Ref. Scott, W.B. and E.J. Crossman, 1973
Remarks Adults inhabit clean, clear gravel riffles and runs of small rivers. Ammocoetes occur in quiet water over sand, silt and debris. Non-parasitic, the adults and possibly the larger ammocoetes in the resting stage do not feed (Ref. 1998). Ammocoetes feed on diatoms, protozoans, green algae, detritus, and pollen. The intestine is nonfunctional (Ref. 1998).
