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.

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.

Trematoda, commonly known as flukes, primarily move using their muscular bodies and cilia. They possess a layer of ciliated cells that help them glide through their aquatic environments. In addition, their muscular contractions allow them to navigate through tissues in their hosts. Some species may also utilize a form of creeping movement by contracting and expanding their body.

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.

Flukes belong to the phylum Platyhelminthes, which encompasses flatworms. Within this phylum, they are classified under the class Trematoda. Flukes are further divided into various orders and families, such as Opisthorchiformes and Fasciolidae, depending on their specific characteristics and life cycles. They are primarily parasitic and inhabit various hosts, including humans and livestock.

Flukes belong to the group of invertebrates known as flatworms, specifically within the class Trematoda. They are parasitic organisms that typically inhabit the bodies of various hosts, including humans and animals. Flukes have complex life cycles that often involve multiple hosts and can cause various health issues in their hosts.

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.

Flatworms belong to the phylum Platyhelminthes and include several classes, the most notable being Turbellaria (free-living flatworms), Trematoda (flukes), and Cestoda (tapeworms). They are characterized by their flattened bodies and lack of a coelom. Flatworms are typically found in aquatic environments, though some can inhabit terrestrial habitats. They exhibit a range of lifestyles, from free-living predators to parasitic forms.

Trematodes, commonly known as flukes, are classified within the phylum Platyhelminthes and belong to the class Trematoda. They are parasitic flatworms characterized by their leaf-like shape and complex life cycles, often involving multiple hosts. Trematodes are further divided into several subclasses, including Digenea, which is the largest group, encompassing many species that infect a variety of vertebrates, including humans. They are known for their various adaptations to parasitism, such as suckers and tegument for attachment and nutrient absorption.

Flukes, which are parasitic flatworms belonging to the class Trematoda, typically have life spans that can vary widely depending on the species and environmental conditions. Some fluke species can live for several months to a few years within their hosts, while others may survive longer. For instance, the liver fluke (Fasciola hepatica) can live up to 10 years in its host. Overall, the longevity of flukes is closely tied to their life cycle and the survival of their hosts.

Representative organisms of flatworms belong to the phylum Platyhelminthes and include three main classes: Turbellaria (free-living flatworms like planarians), Trematoda (parasitic flukes), and Cestoda (tapeworms). Planarians are known for their regenerative abilities, while flukes often have complex life cycles involving multiple hosts. Tapeworms are characterized by their segmented bodies and parasitic lifestyle, typically residing in the intestines of their hosts. These organisms exhibit a range of adaptations for their diverse habitats and lifestyles.

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.

The coelom of liver flukes, which are parasitic flatworms belonging to the class Trematoda, is often considered to be absent or greatly reduced. Instead of a true coelom, liver flukes possess a solid body structure filled with parenchyma, which is a form of connective tissue. This body plan reflects their adaptations to a parasitic lifestyle, where they rely on their host for many functions that other organisms might perform independently within a coelomic cavity. Thus, liver flukes exemplify acoelomate organisms, lacking a true body cavity.

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.
