Answer:
Planaria, also known as planarian worms, are not true worms at all. They are members of the flatworm Order Platyhelminthes, in the Class Turbellaria. They are most often found in clean, undisturbed pond water or underneath moist rocks. At first glance, their simple adaptations for life don't appear to be very specialized. Their digestive system lacks the long tubes of intestines that we have as humans.

So let's delve into the structure and function of the digestive system in planarian worms, and discover how complex and just plain weird even the simplest anatomical system can truly be.
