Leeches have external signs of segmentation but have little repetition of internal parts pr internal compartments.

No, leeches are parasites.
The three systems that developed in the mesoderm of the planarians are ectoderm, mesoderm, and endoderm. They are usually described as the three germ layers.
Well I only know worms, but I hope it can help you.. bristle worms, earthworms, liver flukes, leeches, hookworms, ringworm, tapeworms, whipworms, pinworms, tricladida, planarians, woodworms... That's all I know!!
Planarians are free living and not parasitic. Other classes of their phylum, including flukes and tapeworms, are parasitic when they live inside another organism.
Leeches have external signs of segmentation but have little repetition of internal parts pr internal compartments.
Type of worms are:* Acoelomorpha * Platyhelminthes (flatworms) * Cestoda (tapeworms)** Trematoda (flukes)** Monogenea ** Turbellaria (planarians)* Acanthocephales * Kinorhyncha (mud dragons)* Annelida (segmented worms) * Polychaeta** Oligochaeta ** Hirudinida (leeches)* Nemertea (ribbon worms) * Echiura (spoon worms) * Sipuncula (peanut worms) * Nematoda(roundworms)* Nematomorpha (horsehair worms or gordian worms) * Priapulida (penis worms) * Gnathostomulida (jaw worms)

Planarians have bilateral symmetry.
Yes, planarians are non-parasitic flatworms
Planarians are neither parasitic or segmented. They are flatworms.
What are blood flukes?
The structures that enable planarians to expel liquid waste are normally pores. The pores are found on the dorsal surface of the planarians.
Planarians eat decaying organic matter found on the bottom of streams and ponds.
There are many types of flukes for different animals. In humans, we can be infected with a couple of types of liver flukes, a lung fluke, and blood flukes.
