What is the habitat of most of the class Trematoda?
habitat. Liver flukes are found in swampy, generally wet freshwater areas inhabited by snails, especially of the species Lymnaea truncatula, Stagnicola bulimoides, and Fossaria modicella.

What is the habitat of blood flukes?
blood fluke, any of certain parasitic flatworms that live in the veins of the host organism.
Where do fluke worms live?
Flukes can be found in any place where untreated human waste is utilized as manure. Few flukes (Fasciola hepatica) live on the gills, skin, or outside of their hosts, while others, like blood flukes (Schistosoma), live inside their hosts.
What are the characteristics of Trematoda?
Trematodes are flattened oval or worm-like animals, usually no more than a few centimetres in length, although species as small as 1 millimetre (0.039 in) are known. Their most distinctive external feature is the presence of two suckers, one close to the mouth, and the other on the underside of the animal.

What is meant by blood fluke?
noun. any parasitic flatworm, such as a schistosome, that lives in the blood vessels of humans and other vertebrates: class Digenea. See also trematode.
Where are blood flukes a common problem?
Geographic Distribution. Schistosoma mansoni is found primarily across sub-Saharan Africa and some South American countries (Brazil, Venezuela, Suriname) and the Caribbean, with sporadic reports in the Arabian Peninsula. S. haematobium is found in Africa and pockets of the Middle East.

Flukes
Fasciola hepatica/Class
How many species of trematoda are there?
Trematoda is a class of 15,000–20,000 species and include two subclasses, the Aspidogastrea and the Digenea (Gibson et al., 2014). The Aspidogastrea comprise fewer than 100 species. They are parasites of the alimentary canal mainly of fishes and turtles.
How many species of Trematodes exist?
All trematodes are parasitic, and most adult trematodes parasitize vertebrates. Around 9000 species have been described.
What is the life cycle of a trematode parasite?
Individual trematode parasites life cycles may vary from this list. Trematodes are released from the definitive host as eggs, which have evolved to withstand the harsh environment Released from the egg is the miracidium. This infects the first intermediate host in one of two ways, either active or passive transmission.
What is the primary host of the trematodes?
The primary host, where the flukes sexually reproduce, is a vertebrate. The intermediate host, in which asexual reproduction occurs, is usually a snail . The trematodes or flukes include 18,000 to 24,000 species, divided into two subclasses.
What is the pathophysiology of trematodes in reptiles?
The reptile hosts often acquire the parasite through ingestion of vertebrate intermediate hosts that contain encysted metacercariae. Trematodes are usually not considered to be major pathogens in reptiles.
