'''Digenea''' (Gr. ''Dis'' – double, ''Genos'' – race) is a [[Class (biology)|class]] of [[Trematoda|trematodes]] in the [[Platyhelminthes]] [[phylum]], consisting of [[parasitic]] [[flatworm]]s (known as ''flukes'') with a [[syncytium|syncytial]] [[tegument (helminth)|tegument]] and, usually, two [[sucker (zoology)|suckers]], one ventral and one oral. Adults commonly live within the digestive tract, but occur throughout the organ systems of all classes of [[vertebrates]]. Once thought to be related to the [[Monogenea]], it is now recognised that they are closest to the [[Aspidogastrea]] and that the Monogenea are more closely allied with the [[Cestoda]]. Around 6,000 species have been described to date.
