Introduction:

I am studying the phyla Platyhelminthes and the main groups are flatworms, tapeworms, and planarians, how they adapt, reproduce, special appendages, and what's their habitat like. Did you know that tapeworms can grow up to 10 to 12 meters long

Adaptations:
The worms brain and some of its sense organs are located in its head end, the worm can detect objects, food, predators, and mates quickly. Can sense movement really quickly.

Both sexual and asexual reproduction are found in this worm phyla. Many worms reproduce asexually by methods such as breaking into pieces.
Some worms lay there eggs in intestines.

Habitat:
They live in or on a host. Some of these parasites live in water or in intestines of other organisms.

Special Appendages:
If you cut some kinds of worms into pieces, a whole new worm will grow from each piece.
