What is another word for platyhelminthes?
Pronunciation: [plˈatɪhˌɛlmɪnðz] (IPA) 
Platyhelminthes, also known as flatworms, are a diverse group of invertebrates that are found in a variety of aquatic habitats. There are several synonyms that are used to describe these animals, including turbellaria, trematoda, and cestoda. Turbellaria is a name given to the free-living flatworms that are found in marine, freshwater, and terrestrial environments. Trematoda, or flukes, are parasitic flatworms that infect a wide range of hosts, such as fish, birds, and mammals. Cestoda, also known as tapeworms, are another type of parasitic flatworm that reside in the intestines of vertebrates. Despite their differences, all of these organisms have flattened bodies and lack a respiratory or circulatory system.
