Tapeworms are a type of parasitic flatworm that infect the digestive tracts of humans and animals. They are characterized by their long, segmented bodies that can grow up to several meters in length. There are several different species of tapeworms, each with their unique characteristics and habitats, including beef tapeworm, pork tapeworm, fish tapeworm, and dog tapeworm. Slang terms for tapeworms include wormies and belly snakes, while medical terms include cestodes and helminths. While they may sound harmless, tapeworms can cause a range of health problems, including malnutrition, anemia, and even neurological damage if left untreated.
