The larvae, about two cm long, found in fish may infect man from the ingestion of raw fish meat ('Herring worm disease'). Various intestinal symptoms may develop depending upon the location of the invasive larvae. The figure shows a Terranova larva as seen by gastroscope in the stomach wall of a 53- year-old Japanese woman.
