DSC_7196 Pouched lamprey (Geotria australis) NIWA freshwater scientists Don Jellyman and son Phillip, search for lamprey nests in a boulder strewn stream. Once the eggs hatch, the ammocoete larva drift downstream and bury themselves in the mud for the first four years or so of their life, before eventually transforming into macropthalmia, and migrating to the sea.
