Turbellaria , Trematoda and cestoda
The phylum that contains the classes Trematoda, Cestoda, and Turbellaria is Platyhelminthes. These classes are all part of the same phylum due to their similar characteristics, such as being flatworms with bilateral symmetry and simple body structures.
monogenea are ectoparasitic while trematoda are endoparasitic
Flatworms are of the phylum Platyhelminthes. This phylum has three classes: Turbellaria -- predacious worms Trematoda -- known commonly as flukes Cestoda -- tapeworms
The scientific name for flatworms is Platyhelminthes.
There are three main subgroups within the phylum Platyhelminthes: Turbellaria (free-living flatworms), Trematoda (flukes), and Cestoda (tapeworms). Each subgroup consists of various species with unique characteristics and ecological roles.
The scientific name for turbellaria is Turbellaria. Turbellaria is a class of free-living flatworms that belong to the phylum Platyhelminthes.
Platyhelminthes as a phylum is divided into 4 classes. The tapeworm class (Cestoda) is endoparasitic. This means they live parasitically inside a host. There is also the ectoparasitic class Monogenea which lives parasitically on the outside of a host. There are marine specimens and those that live in other moist environments. This is the class Turbellaria.
