Introduction


Flatworms, or Phylum Platyhelminthes, come in many forms- from the parasitic Trematoda and Cestoda (more commonly called flukes and tapeworms), to the non-parasitic Turbellaria class (also known as planarians). They can get into our bodies or the bodies of our animals and cause disease (tapeworms). They are studied by scientists and disected by young children all over the world. Flatworms deep in the ocean have amazing colors. They have no respiratory or circulatory systems, but they do have a primitive brain. The flatworm, despite its boring-sounding name, is an interesting and exciting creature.

Colorful and beautiful flatworms can be found in sea water and fresh water, while the less exotic can be found in the intestines of most animals, including humans. Parasitic flatworms live off a host for most of their life, while non-parasitc flatworms do not need a host to survive. Flatworms eat and get rid of waste through the same opening in their body and they are bilaterally symmetrical. This bilateral symmetry allows them to move forward and have sensory organs in the front. The internet has a large supply of site on flatworms. Here are some of the best.
