Cestoda - Wikipedia Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed into the environment to infect other organisms Species of the other subclass, Cestodaria, are mainly fish-infecting parasites
CDC - DPDx - Taeniasis The adults produce proglottids which mature, become gravid, detach from the tapeworm, and migrate to the anus or are passed in the stool (approximately 6 per day) T saginata adults usually have 1,000 to 2,000 proglottids, while T solium adults have an average of 1,000 proglottids
Tapeworm infections - UpToDate Depending on the species, the adult worm may have hundreds or thousands of proglottids In some species (such as Taenia), the distal segments can separate from the rest of the body, and the proglottids (or the eggs they contain) are passed in the stool
