Page "Strongyloides stercoralis" Paragraph 12

Whereas males grow to only about 0. 9 mm in length, females can be anywhere from 2. 0 to 2. 5 mm.

Both genders also possess a tiny buccal capsule and cylindrical esophagus without a posterior bulb.

In the free-living stage, the esophagi of both sexes are rhabditiform.

Males can be distinguished from their female counterparts by two structures: the spicules and gubernaculum.
