monogenea are ectoparasitic while trematoda are endoparasitic

Trematoda

It belongs to the invertebrate class: Trematoda

trematoda and monogenea

Flukes

Cestoda, Turbellaria, Trematoda, and Monogenea

Trematoda are more evolutionarily advanced because they show the traits of cephalization, an organ system, and have a lophophore. While nematoda have none of these traits.

They enter in through the water.

Trematode-- Any parasitic flatworm of the class Trematoda, as the liver fluke.

class turbellaria isncludes the members which are free living and class trematoda includes parasitic species

The phylum that contains the classes Trematoda, Cestoda, and Turbellaria is Platyhelminthes. These classes are all part of the same phylum due to their similar characteristics, such as being flatworms with bilateral symmetry and simple body structures.

Flatworms are of the phylum Platyhelminthes. This phylum has three classes:

Turbellaria -- predacious worms

Trematoda -- known commonly as flukes

Cestoda -- tapeworms

The scientific name for flatworms is Platyhelminthes.

There are three classes in the platyhelminthes phylum. These classes include Turbellaria, Monogenea, and Trematoda. These classes still break down into orders, families, genus, and species. I'm still looking for the rest.

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.

The phylum with the most species that parasitize humans is Platyhelminthes, specifically the class Trematoda (flukes) and the class Cestoda (tapeworms). These parasites can cause diseases such as schistosomiasis and cysticercosis in humans.

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.

Platyhelminthes as a phylum is divided into 4 classes. The tapeworm class (Cestoda) is endoparasitic. This means they live parasitically inside a host. There is also the ectoparasitic class Monogenea which lives parasitically on the outside of a host.

There are marine specimens and those that live in other moist environments. This is the class Turbellaria.

The simplest bilateral animal is considered to be a flatworm, such as a planarian. These animals have a simple body structure with bilateral symmetry, a central nervous system, and a digestive system. They are an example of simple, yet successful, bilateral organisms.

Planaria, tapeworms and flukes are all classic examples of flatworms. Planaria live in the creeks, flukes live in the livers of sheep, and tapeworms live in the intestines of cows, dogs and even humans.

The flatworms, or Platyhelminthes or Plathelminthes are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates, (having no body cavity), and no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both the ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously.

In traditional zoology texts, Platyhelminthes are divided into Turbellaria, which are mostly nonparasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been proven not to be monophyletic, this classification is now deprecated. Free-living flatworms are mostly predators, and live in water or in shaded, humid terrestrial environments such as leaf litter. Cestodes (tapeworms) and trematodes (flukes) have complex life-cycles, with mature stages that live as parasites in the digestive systems of fish or land vertebrates, and intermediate stages that infest secondary hosts. The eggs of trematodes are excreted from their main hosts, whereas adult cestodes generate vast numbers of hermaphroditic, segment-like proglottids which detach when mature, are excreted, and then release eggs. Unlike the other parasitic groups, the monogeneans are external parasites infesting aquatic animals, and their larvae metamorphose into the adult form after attaching to a suitable host.

how are parasites transmitted? There are many different types of parasites and each type uses a different mode of transmission.

Parasitic worms can enter the human body through pets and other animals. Dogs are carriers of echinococcus, a type of tapeworm. The tapeworm eggs tend to spread over a dogs fur through its anus. Toxoplasma gondii parasite is found in cat feces and you can get toxoplasmosis through this parasite.

Certain parasites like protozoa are transmitted via contaminated drinking water. This contamination is by fecal matter of an infected person. This mode of transmission is occurs more frequently in developing countries due to poor sanitation and bad personal hygiene. However, rural areas of the United States are not spared by protozoa infestation. Some parasites do not need to be consumed in order to be transmitted. For instance, the trematoda fluke can only be transmitted when the skin comes in contact with contaminated water.

However, the most common way to getting parasitic infestation is through food consumption. Vegetables are being grown in farms that use human waste for fertilizers and unless these vegetables are thoroughly washed, you can parasitic infection by eating these contaminated vegetables. Another way of getting is from restaurants where food handlers can have fecal matter hidden under their nails even without them knowing it.

Another method of transmission is through soil. There are some parasites that spend their egg stage in soil; and if you walk barefoot or sit on fecal-contaminated soil, you can get infected by parasites like hookworms or strongyloides, which penetrate the skin and then make their way to the intestine.

Taxonomists, biologists who specialize in the field of classification, use several categories when classifying organisms. A domain is the highest level of organization. Within a domain, there are kingdoms. within kingdoms, there are phya. within phyla are classes. within classes are orders. within orders are families. families contain genera (singular genus). finally, one genius contains one or more species.
