Males reach a length of 10–17 mm and possess a bursa copulatrix with three lobes and two similarly long spicula (~200 μm) plus a gubernaculum. Females reach a length of 12–24 mm. Both sexes appear reddish-yellowish and live in the muscular stomach below the keratinoid layer of the stomach of geese and some other waterfowls. The eggs measure 80–110 μm × 50–80 μm and contain many blastomeres when excreted.
