Trematoda is a class of flatworms known as flukes or trematodes. [1] They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, are mollusks and usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. [1]

Also known as flukes, trematodes are a group of parasitic flatworms (leaf-shaped). Although they are mostly associated with such aquatic fauna as fish and mollusks, they also affect various vertebrates as part of their indirect life cycle.

Fluke, any member of the invertebrate class Trematoda (phylum Platyhelminthes), a group of parasitic flatworms that probably evolved from free-living forms millions of years ago. There are more than 10,000 species of flukes. They occur worldwide and range in size from about 5 millimetres (0.2 inch)

Trematodes are parasitic flatworms of the class Trematoda, specifically parasitic flukes with two suckers: one ventral and the other oral. Trematodes are covered by a tegument, that protects the organism from the environment by providing secretory and absorptive functions. The life cycle of a typical trematode begins with an egg.

Most trema­todes have com­plex life cy­cles, with lar­val stages par­a­sitiz­ing one or more species that are dif­fer­ent from host of adults. Lar­val stages of some med­ically im­por­tant species in­clude miracid­ium, redia, cer­caria, and metac­er­caria. Most trema­todes are en­dopar­a­sites.

Mar 27, 2024 · Trematodes, also called flukes, cause various clinical infections in humans. The parasites are so named because of their conspicuous suckers, the organs of attachment (trematos means "pierced...

The Trematoda is a class within the phylum Platyhelminthes that contains two groups of parasitic worms, commonly referred to as flukes. The Trematoda are estimated to include 18 000 [1] to 24 000 [2] species, and are divided into two subclasses. Nearly all trematodes are parasites of molluscs and vertebrates.

Jun 11, 2018 · Trematodes and flukes are the common names for the flatworms in the class Trematoda, phylum Platyhelminthes. Trematodes have most of the same features as other classes of Platyhelminthes. They are acoelomate , unsegmented, bilaterally symmetrical triploblasts that are flattened dorsoventrally .
