Taenia (Tapeworm) and Fasciola (liver fluke) are examples of parasitic platyhelminthes. Peculiar features in parasitic platyhelminthes are as follows.
They have dorsiventrally flattened body and bear hooks and suckers to get attached inside the body of the host.
Their body is covered with thick tegument, which protects them from the action of digestive juices of the host.
The tegument also helps in absorbing nutrients from the host’s body.
