Flatworms are worms that have a soft body and no backbone. They are found in the kingdom known as animalia and the phylum called platyhelminthes. They have a bilateral symmetry and three main cell layers. They also have a distinct brain and specialized digestive system.

They also have a specialized excretory system which means that these systems are not simple. They do not have body cavities containing internal organs and they do not have specialized circulatory and respiratory organs.

There are common examples of flatworms found around the world. One type is called the tapeworm. Sometimes, the tapeworm can get into a person’s or animals’ system. This can cause problems for the person or animal and make them very sick.

Flatworms, as the name implies, do not have vertebra and are soft-bodied worms. They do not have circulatory nor respiratory systems just nervous and digestive systems. There are three types of flatworms - the Trematoda, Cestoda, and Turbellaria. The Trematoda class consists of parasitic flatworms that need two hosts to complete their life cycle also knows as flukes. The class Cestoda consists of tapeworms.

These tapeworms invade humans’ and animals’ digestive tract to cause infection and disease. But for the class Turbellaria, flatworms in this class are not parasitic compared to the two. The planaria flatworms are usually nonparasitic and feed on bacteria, protozoa, crustacea, or smaller worms.
