Cestoda

Cestoda, commonly known as tapeworms, are a class of parasitic flatworms that live in the intestines of animals, including humans. They have long, segmented bodies that can grow quite large, with each segment containing reproductive organs. Tapeworms attach to the host's intestinal walls using specialized structures called scolex, which often have hooks or suckers. They absorb nutrients directly through their skin, relying on the host's digestive system. Infection typically occurs through contaminated food or water, and symptoms can range from mild to severe. Proper hygiene and food safety help prevent tapeworm infections.
