👉 Platyhelminthes are small, parasitic worms that live in the digestive systems of certain animals. They feed on parasites and other microorganisms found in their host's body, such as bacteria, fungi, and viruses. These parasites can cause a variety of diseases, including malaria, lymphatic filariasis, and schistosomiasis. Platyhelminthes are important for the survival of many species of animals, and their control is crucial for maintaining biodiversity and ecological balance.
