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 ...
Depending on the species, members of class Turbellaria either exist as free-living organisms or parasites. For instance, members of the order Temnocephalida exist as either entirely commensals or parasites. One of the best examples of a free-living (opportunistic) species in this order is the Temnosewellia minor.
Platyhelminthes are commonly known as flatworms or tapeworms. They are a group of soft-bodied invertebrate animals. As a matter of fact, there are around 20,000 species of these animals. A few of these live as parasites on humans and other animals.
The animal kingdom is a wonderful one. It has so many different members, that are all equally interesting to study. Read this article on platyhelminthes examples to know more about this fascinating phylum.
The flatworms, flat worms, Platyhelminthes, Plathelminthes, or platyhelminths (from the Greek πλατύ, platy, meaning "flat" and ἕλμινς (root: ἑλμινθ-), helminth-, meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates.Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and ...
Examples of Phylum Platyhelminthes. 1. Planaria (Dugesia) 2. Liver fluke 3. Tape worm (Taenia solium) Parasitic adaption. The parasitic adaptations of flatworms are as following. 1. They have thick body covering, which protects them from host body. 2.
Flatworms are a group of very simple animals limited in size by a lack of an internal transport system, they can grow quite long though. The group contains many unpleasant internal parasites of almost every vertebrate species including man. They often alternate between host species as part of their life cycle which helps them spread more effectively.
A few organisms belonging to these species cause severe diseases such as Schistosomiasis, or snail fever. It is one of the most dangerous diseases in tropical countries. Taeniasis is another disease caused by Tapeworms. Examples of Platyhelminthes. The examples of organisms belonging to phylum Platyhelminthes are: Dugesia (Planaria)
Platyhelminthes or flatworms are dorsoventrally flattened bilaterally symmetrical tripoblastic but acoelomate animals which have a blind sac body plan.There are about 13,000 species, most of which are parasitic, a few commensal or free living. The free living forms occur in both fresh water and marine habitats.
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.
