Flatworm The flatworms, or 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.

- Flatworms belong to the Phylum Platyhelminthes (Latin for Flatworms, although it sounds much more official), whose characteristics shape - flat - is an evolutionary answer to a problem of multicellular life: as an animal gets bigger, the inside cells get farther and farther away from the outside, so that oxygen gets depleted before it reaches them ...

- Platyhelminthes. The parasitic flatworms of class Trematoda, also called flukes, have oral suckers, sometimes supplemented by hooks, with which they attach to their vertebrate hosts.

The Phylum Acanthocephala Members of the phylum Acanthocephala are important parasites of domesticated and wild animals. Adult acanthocephalans are internal parasites, living in the small intestine of their vertebrate hosts. Acanthocephalans are typically elongate, cylindric worms, tapering on both ends. One acanthocephalan (M. hirudinaceus) can measure up to 70 cm in length.

Flatworms Platyhelminthes are also known as flatworms because they are worms with a flat body. This is the main external morphological feature that differentiates them from nematodes (roundworms).

Platyhelminthes are a simple phylum made up of invertebrate, unsegmented, soft-bodied organisms Flat worms are soft-bodied invertebrate animals from the platyhelminthes phylum. They take in oxygen but have no formal respiratory system.This is because they are very simple animals. They went through such small evolution that they never developed a complex respiratory system.lat worms are soft-bodied invertebrate animals from the platyhelminthes phylum. They take in oxygen but have no formal respiratory system.

Platyhelminthes: Body Cavity & Movement So what does it mean to be a 'platy' worm? Well, their shape comes from the fact that they, unlike earthworms, have no coelom (otherwise known as a fluid-filled body cavity). Therefore, Platyhelminthes are acoelomates ('a' meaning 'without'). So why is the presence or absence of a fluid-filled body cavity important?

Flatworms Platyhelminthes are also known as flatworms because they are worms with a flat body. This is the main external morphological feature that differentiates them from nematodes (roundworms).urbellarians are free-living platyhelminthes and their main representative is planaria (Dugesia tigrina). Trematodes are parasites, which live inside a host,. The schistosome (Schistosoma mansoni) that causes schistosomiasis is an example of one.

Differences between Platyhelminthes, Nematoda, and Annelida? Best Answer: Platyhelminthes consists of flat worms. They are dorsoventrally flattened. Have a gastrovascular cavity or no digestive system. No segments. Example) Planerian Nematoda is an unsegmented pseudocoelomate. No circulatory system. Consists of Roundworms. Annelia consists of segmented worms.

- The word ‘helminth’ is a general term meaning ‘worm’, but there are many different types of worms. Prefixes are therefore used to designate types: platy-helminths for flat-worms and nemat-helminths for round-worms.

- Explain the basic body plan of members of the phylum Platyhelminthes. Identify representatives of the classes Turbellaria, Trematoda, and Cestoda. Compare and contrast the anatomy and morphology of free-living and parisitic flatworms. Describe the symmetry of this group. Platyhelminthes is a phylum composed of three classes of flatworms. The class Turbellaria (planarians) is free-living, while the remaining classes including the Trematoda (flukes) and Cestoda (tapeworms) are parisitic. Members of the phylum Platyhelminthes are dorsoventrally flattened.

- Nematodes, also called roundworms, are members of the animal phylum Nematoda. These worms have a complete digestive system and are more complex than the flatworms (phylum Platyhelminthes) but lack a circulatory system and other advanced features found in the annelids (segmented worms).

Platyhelminthes Platyhelminthes. Members of the phylum Platyhelminthes are flatworms, such as the planarian. Grubs and tapeworms are other examples of flatworms. Flatworms display bilateral symmetry; that is, the left and right halves of the body are mirror images of one another.Another characteristic of the platyhelminthes is cephalization.Cephalization means that one end of the animal functions as a head.The “head” contains a mass of nerve cells that acts as a brain and specialized regions for sensing light, chemicals, and pressure.nother characteristic of the platyhelminthes is cephalization.Cephalization means that one end of the animal functions as a head.

When the eggs are fully developed, the proglottids separate and are excreted by the host.
