Tapeworm

 The Flatworm groups belongs to Phylum Platyheminthes. As their name suggests, they are flat and ribbon-like organisms. Flatworms often found in freshwater, in wet places and marine waters They include the free-living or nonparasitic worms, the parasitic flukes, and the tapeworm group.

Roundworm They are a diverse animal phylum inhabiting a

very broad range of environments. Nematode species can be difficult to distinguish, and although over 25,000 have been described, of which more than half are parasitic, the total number of nematode species has been estimated to be about 1 million. Unlike the phylaCnidarians and Platyhelminthes (flatworms), nematodes have tubular digestive systems with openings at both ends.

Segmented Worm The annelids, also known as the ringed

worms or segmented worms, are a largephylum, with over 17,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies through natural selection, some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments.
