Greek: amido = enlarged, non-central; stoma = mouth; Latin: anser = goose.

Worldwide among farmed and free living geese.

Morphology/Life Cycle

The adults of A. anseris are characterized by a mouth capsule with three sharp teeth. 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. Related species are A. acutum in the muscle stomach of geese and ducks (worldwide) and Epidomostomum uncinatum(with a reduced mouth capsule in the muscular stomach of ducks and geese (worldwide). The larva 3 develops inside the eggs when excreted on soil. At temperatures of ~20 °C it takes about 3 weeks until this...
