Ammocoetes and adults found in rivers. Ammocoetes occur in substrates of fine sand with abundant organic detritus along the river banks. Metamorphosis occurs between August and March and recently metamorphosed adults enter marine waters during austral winter (June-August) at about 14.3 cm TL. Anadromous. Adults parasitic on fishes in marine waters. Mature adults occur in continental marine waters between September and December (Ref. 89241).
