Platyhelminthes (Flatworms) General characteristics: – Body plan: acoelomate, bilateral symmetry Habitat: aquatic Nutrition: many are parasites, feed off.
Animalia. General characteristics The body segmented, the segments usually grouped in two or three rather distinct regions. Paired segmented appendages.
