Platyhelminthes is a very interesting phylum that contains nearly 20,000 species. These organisms are generally hermaphrodites, meaning they can have both male and female sexual organs and can ...

Phylum Platyhelminthes. Phylum Platyhelminthes is composed of the flatworms: acoelomate organisms that include many free-living and parasitic forms. Most of the flatworms are classified in the superphylum Lophotrochozoa, which also includes the mollusks and annelids. The Platyhelminthes consist of two lineages: the Catenulida and the Rhabditophora.
Platyhelminthes are triploblastic, bilaterally symmetrical, dorsoventrally flattened, acoelomate flatworms with organ grade of construction without a definite anus, circulatory, skeletal or respiratory system but with Protonephridial excretory system and mesenchyme filling the space between the various organ of the body.
Flatworms belong to the phylum Platyhelminthes, literally meaning "flatworms" in Latin. Flatworm species are divided into three classes: Turbellaria, Trematoda and Cestoda. All flatworms, according to Cool Galapagos, are hermaphroditic, soft-bodied worms with rudimentary nervous systems, no respiratory or ...
Phylum Aschelminthes. Aschelminths can be free-living or parasitic. The free-living organisms are extremely abundant in soils and sediments and they feed on bacteria.While some others are plant parasites and can cause disease in crops that are economically important. The others are parasites that can be found in animals and human beings.
