Marine flatworms typically have a flat, ribbon-like body with distinct bilateral symmetry, while nudibranchs have a soft body with external gills on their back and often colorful patterns. Additionally, nudibranchs belong to the mollusk group, while marine flatworms do not.
Common flatworm that is not a parasite?
Planarians are a common type of flatworm that are not parasites. They are often found in freshwater environments and are known for their regenerative abilities. Planarians are carnivorous and feed on small organisms like insects and other invertebrates.
Flatworms are themselves a rather primitive organism. However, having the orientation of anterior-posterior allows them to move their anterior towards food and their posterior away from irritants, which are movements that organisms without this orientation can't do.
What is the scientific name for the species of flatworms?
There are four common types of flat worms. One of them is non parasitic. That is the Turbellaria group. The other parasitic ones are Cestoda, Tremadota, and Monogenea.
Are flatworms born from an egg?
no, they care born from seeds in certain flowers like the hibiscus, water lily and dahlia
What are the major classes of flatworms?
Flatworms are divided into two groups, parasitic and nonparasitic. The parasitic types, which live off of other organisms, consist of Cestoda, Trematoda, and Monogenea flatworms.
Research has shown that the flatworm communicates via the gap junctional channels. This also applies to the other types of worms as well.
What is the waste product of flatworms?
