👉 Tapeworms are small, round worms that can grow up to 1 cm in diameter. They are typically found in freshwater habitats such as lakes, rivers, and streams. Tapeworms feed on organic matter in water bodies, including feces, which they break down into a slimy slime that is then spread throughout the water column. Tapeworms are often associated with human infections due to their ability to transmit diseases like roundworm infestations or giardiasis.
