What are the peculiar features that you find in parasitic platyhelminthes?

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.

Hooks and suckers are present in parasitic platyhelminthes. Suckers facilitate the sucking of blood from the host.

Hooks and Suckers are present in parasitic Platyhelminthes. Some of them absorb nutrients from host directly through their body surface, e.g.: Taenia (Tapeworm), Fasciola/liver fluke). 

In parasitic platyhelminthes hooks and suckers are present. Suckers help the parasite, in sucking the blood from the host.
