When a proglottid becomes old and unable to absorb any more nutrition, it is released and is passed through the host's digestive tract.

A proglottid can copulate with itself, with other proglottids in the same worm, or with proglottids in other worms, and hypodermic fertilization sometimes occurs.

In the feces are the gravid proglottids that house the " T . pisiformis " eggs that will eventually be released form the proglottid onto nearby vegetation.

The small neck region, directly behind the scolex, consists of an undifferentiated tissue region of proglottid proliferation, leading into a zone of increasing and continuous proglottid differentiation.

Their scolex does not have hooked rostellum like the " H . nana " species but they do have similar unilateral genital pores and 3 testes per proglottid.

The layout of proglottids comes in two forms : craspedote, meaning any given proglottid is overlapped by the previous proglottid, and acraspedote, indicating the proglottids are not overlapping.

The adult tapeworm ranges in length from 3 mm to 6 mm and has three proglottids ( " segments " ) when intact an immature proglottid, mature proglottid and a gravid proglottid.
