Adult worms are usually {{convert|3|–|5|cm|in}} long, with females being larger than males as is typical of nematodes. The thin, clear majority of the body (the anterior, whip-like end) is the esophagus, and it is the end that the worm threads into the mucosa of the colon. The widened, pinkish-gray region of the body is the posterior, and it is the end that contains the parasite's intestines and reproductive organs.
''T. trichiura'' eggs are [[prolate spheroid]]s, the shape of the balls used in Rugby and [[Gridiron football]]. They are about {{cvt|50|-|54|μm|lk=in}} long and have polar plugs (also known as refractile prominences) at each end.{{citation needed|date=May 2021}}
