This nematode (~9 × 12 mm) is one of the most important nematode parasites of reindeer/caribou (Rangifer tarandus) with one semi-domesticated and several wild subspecies. It parasitizes in the abomasum of caribous and of sheep sharing common pastures, The extraintestinal stages are able to survive the low temperatures in the circumpolar regions. A peculiar morph (O. arctica) is especially common in circumpolar regions. The development in the reindeer host is arrested, but infectious larvae may be ingested from pasture all year round.
