Adult tapeworms occur in the intestine of various vertebrates including fish. Their bodies are typically long and flat, consisting of many segments called proglottids, where each is a gamete-producing factory.
What are the types of Proglottids?
Thus, the three distinct proglottids are immature proglottids towards the neck, mature proglottids in the middle, and gravid proglottids at the posterior end. A hermaphroditic species, each mature proglottid contains a set of male and female reproductive systems.
What is a proglottid in a tapeworm?
The adult tapeworm is made up of many small segments, called proglottids, each about the size of a grain of rice. Adult tapeworms may measure 4-28 inches in length. As the tapeworm matures inside the intestine, these segments (proglottids) break off and pass into the stool.
What is Proglottids in Taenia solium?

When retrieved and further analyzed, it was found to be a proglottid of Taenia saginata, the beef tapeworm. The scolex and majority of the worm are present in the small bowel, with the head usually residing in the jejunum or ileum. Each segment, known as a proglottid, has a complete set of reproductive organs.
Are Proglottids alive?
The sum of the proglottids is called a strobila, which is thin and resembles a strip of tape; from this is derived the common name "tapeworm". Proglottids are continually being produced by the neck region of the scolex, as long as the scolex is attached and alive.
How are Proglottids produced?
Once ingested, cysticerci attach to the small intestine and develop into adult tapeworms over the course of 2 months. The adult tapeworms produce proglottids that mature, detach, and migrate to the anus and are then passed in the feces.
What are Proglottids and its type in Taenia?
More than 100 species are recorded. They are morphologically characterized by a ribbon-like body composed of a series of segments called proglottids; hence the name Taenia (Greek ταίνια, tainia meaning ribbon, bandage, or stripe). The anterior end of the body is the scolex.

proglottis
One of the segments of a tapeworm, containing both male and female reproductive organs.
proglottid
One of the segments of a tapeworm, containing both male and female reproductive organs. The proglottides increase in size progressively as they become remote from the head of the worm.
proglottid
one of the divisions or apparent segments of a tapeworm, formed by transverse budding in the neck region, which remain connected as they move backwards, increasing in size and maturing. Eventually the proglottid is cut off and is shed from the gut of the host. Each proglottid contains male and female sex organs.
