Appearance: Tapeworms have a distinctive ribbon-like appearance, with a small head called the scolex, which contains hooks or suckers used to attach to the intestinal walls. Behind the scolex is a series of segments known as proglottids, each of which contains reproductive organs. As the tapeworm matures, these proglottids are shed and released in the host's feces.
Lifecycle: The tapeworm lifecycle begins when eggs are excreted in the feces of an infected host. These eggs can survive in the environment until they are ingested by a new host, usually through contaminated food or water. Inside the host, the eggs hatch into larvae, which then migrate to various tissues before maturing into adult worms in the intestines.
