The ova is yellowish in color. The egg is about 70–85&nbsp;μm long by 44&nbsp;μm wide, and the early stages of cleavage contain between 16 and 32 cells. The adult female is {{convert|18–30|mm|in|frac=8}} long and is easily recognized by its trademark "barber pole" coloration. The red and white appearance is because ''H. contortus'' is a blood feeder, and the white ovaries can be seen coiled around the blood-filled intestine. The male adult worm is much smaller at {{convert|10–20|mm|in|frac=16}} long, and displays the distinct feature of a well-developed copulatory bursa, containing an asymmetrical dorsal lobe and a Y-shaped dorsal ray.
