Which flatworms are called endoparasites?

Endoparasites are organisms that live in the host’s body. Endo means inside. Flatworms are divided into free-living and parasites. The first are white planaria. All the rest of the listed ones are parasites.

The liver fluke larva forms a protective membrane and turns into a cyst. During sexual reproduction of white planaria, after fertilization, the eggs are covered with a special layer, forming a cocoon. The larva of the pork tapeworm at one of the stages of the cycle turns into a Finn. The fluke larva also forms a protective shell and enters the cyst stage.
