What are the main characteristics of flatworm?
What are the main characteristics of flatworm?
The main characteristics of flatworms (Figure below) include:
- Flatworms have no true body cavity, but they do have bilateral symmetry.
- Flatworms have an incomplete digestive system.
- Flatworms do not have a respiratory system.
- There are no blood vessels in the flatworms.
What are the characteristics of Turbellaria?
Class Turbellaria(flatworms)
- True bilateral symmetry.
- Dorso-ventral flattening of the body.
- Unsegmented.
- Ciliated epidermis.
- System of sheathed nerve fibers.
- Parenchyma between the epidermis and the gastrodermis.
- Some cephalization.
- Blind ending gut.
What are the characteristics of trematoda?
Trematodes are flattened oval or worm-like animals, usually no more than a few centimetres in length, although species as small as 1 millimetre (0.039 in) are known. Their most distinctive external feature is the presence of two suckers, one close to the mouth, and the other on the underside of the animal.

What are five characteristics of phylum Platyhelminthes?
Characteristic features of Phylum Platyhelminthes
- Their body is dorsoventrally flattened.
- They exhibit bilateral symmetry.
- Also, they are triploblastic, with three germ layers.
- They do not have a body cavity and are acoelomate.
- The body is soft and unsegmented.
- They are mostly parasitic with a few free-living.
Which of the following traits characterize the phylum Platyhelminthes?
Platyhelminthes have the following important characteristics: They are triploblastic, acoelomate, and bilaterally symmetrical. They may be free-living or parasites. The body has a soft covering with or without cilia.

TurbellariaTurbellaria / Scientific name
What is the life cycle of Turbellaria?
Life Cycle Turbellarians are hermaphrodites, meaning that each individual animal possesses both male and female anatomy, and when two turbellarians mate, they inseminate one another. Some species lay eggs encased in round capsules on short stalks.
Which classification fits a flatworm that is free-living?
Turbellaria are free-living flatworms. This means that they are able to find and digest their own food, and they do not depend on a host organism. An example of a turbellarian is shown in Figure below.

What is the difference between Monogenea and Platyhelminthes?
Phylum: Platyhelminthes – Monogenea belong to the Phylum Platyhelminthes. They are bilaterally symmetrical and exist as free-living or parasitic organisms. They are also acoelomate with a dorsoventrally flattened body as well as a soft outer covering. Superclass: Neodermata – Neodermata is a large group that largely consists of parasitic flatworms.
What is the classification of Monogenea?
With over 4,000 species, the class Monogenea consists of parasitic flatworms that belong to the Phylum Platyhelminthes. They are commonly found in aquatic habitats where the majority of species exist as ectoparasites of fish and other organisms.
Is Monogenea a trematode?
Monogenea are in the order Platyhelminthes. They are not trematodes but may incorrectly be referred to as “monogenean trematodes,” even by pathologists who know better. Monogenea are characterized by the opisthaptor, the posterior holdfast organ. Monogenea consists of two groups, monopisthocotyleans and polyopisthocotyleans.
What is a monogenetic fluke?
Monogenetic flukes spend their entire life cycle as parasites on a single host, often on the gills and skin of fish; they include no human parasites. They hold on to the fish by the use of hooks and attachment organs at the posterior end. Most of the parasite’s body space is devoted to the hermaphroditic reproductive system.
