The main species present in Australia is Trichuris discolour with T. ovis and T. globulosa being uncommon. Whipworms are white, 40–80 mm long and inhabit the blind gut (caecum) of cattle, sheep and goats. The adult body is whip-like with an anterior end that is fine and hair-like, and embedded in the wall of the large intestine while the posterior end is stout and free in the lumen of the gut. Whipworms occur occasionally in all cattle production areas of Australia.
