1 They have a circulatory system and a digestive system. 2  Flatworms, roundworms, and segmented worms are all invertebrates. 3  Some species of each type of worm are free-living, meaning they are not dependent on another organism for food. 4  Segmented worms are the most complex animals of these three invertebrates. Students will then continue with their Internet research to compare flatworms, roundworms, and segmented worms by completing the Worm Comparison worksheet. 2  They should use their research to find more information in order to describe how these three types of worms are similar and how they are different.
