| But once a tapeworm matures, it begins releasing rather large, semi-self-propelled egg-filled sacks called proglottids. |
| As mentioned earlier, tapeworm proglottids exit the body along with bodily wastes to search for a new host in which to proliferate. |
| The stool examination revealed small, white, seed-like structures which were identified as proglottids, measuring 7mm by 3mm and tapered at both ends. |
| The strobila is made up of anywhere from a few to more than one thousand proglottids but usually contains several dozen. |
| The number of proglottids may vary from three in some species to several hundreds in others. |
| The eggs or gravid proglottids are excreted in the feces and consumed by the pig to develop into larvae. |
