This comic hopes to shed some light on the difficult life of a tapeworm.
What Is the Life Cycle of the Beef Tapeworm? The adult beef tapeworm is usually a whopping 15 to 30 feet long (4.5 to 9 meters) and lives in the small intestine. An infected person usually has only one or two worms. The tapeworms use their head, called the scolex, to attach themselves to the intestinal wall.
The life cycle of a tapeworm starts as an egg, which is consumed and stored by an invertebrate. The invertebrate is then consumed by a vertebrate host in which the tapeworm develops and breeds. Some exceptions to this general pattern exist, such as when eggs are retained and hatch within the vertebrate host.
The cestodes (tapeworms) Taenia saginata (beef tapeworm) and T. solium (pork tapeworm). Taenia solium eggs can also cause cysticercosis. Life Cycle: Taeniasis is the infection of humans with the adult tapeworm of Taenia saginata or Taenia solium. Humans are the only definitive hosts for T. saginata and T. solium.
The life cycle of a human tapeworm: 1. A man eats a poorly cooked piece of beef containing the encysted bladderworm (tapeworm cyst) in the skeletal muscle tissue. The young tapeworm attaches to the man's intestinal wall by its smaller, anterior end called the scolex. The scolex anchors the the tapeworm to the host's intestinal wall by four suckers.
The life cycle of A. perfoliata requires an intermediate host. Infected horses pass tapeworm eggs onto the pasture where they are consumed by free-living oribatid mites. The eggs develop into larvae within the mite until the mite is ingested by a grazing horse, allowing the larvae to be released into intestine.

Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species - and the best-known - are those in the subclass Eucestoda; they are ribbonlike worms as adults, known as tapeworms.Their bodies consist of many similar units, known as proglottids, which are essentially packages of eggs which are regularly shed into the environment to infect other organisms.
The adult tapeworm sheds its eggs, and the infested canine excretes tapeworm eggs in their scat or feces. Stage II of the tapeworm life cycle is the transmission of the eggs to the intermediate host, most often a rabbit, rodent or hare. This occurs through contamination of their fur with dog feces, or through contaminated food.
The term tapeworm is commonly restricted to members of the class Cestoidea. The tapeworms (cestodes) Taenia saginata (beef tapeworm) and Taenia solium (pork tapeworm) are of significance to human being as taeniasis occurs when raw or undercooked, unfrozen beef or pork are eaten.
