The Pacific lamprey lives in the demersal, anadromous, freshwater, brackish, marine, depth range 0 - 1100 m environment.

Pacific lampreys begin their life cycle as an ammocoete or larvae, usually within a freshwater stream. Ammocoetes burrow tail first into mud or soft substrate where they filter feed on algae and organic matter. More
