More specifically, marine bivalve molluscs play a key role as hosts for larval stages of digeneans
, with trematodes being the main parasites both in terms of numbers and in the damage and pathological conditions they cause (Thieltges et al.
Two new species of digeneans
(Lecithasteridae and Haploporidae) of the intertidal blenny Scartichthys viridis (Valenciennes) from the central coast of Chile.

In general, digeneans
and nematodes larvae dominate the endohelminth parasite fauna of forage fish species (Marcogliese et al.
The pathogenic significance of digeneans
in fishes is much more pronounced in infections by metacercariae than by adults because these encyst in any tissue or organ, except in cartilage or bones, weak the host (EIRAS, 1994; THATCHER, 2006).
proops to the probable intermediate hosts of digeneans
were recovered from the small intestine, intestinal caecum, and rectum of the bird, and the worms were fixed under cover slip pressure in 5% hot formalin and stored in 70% ethanol.
They are unique among digeneans
by having a furcocystocercous cercaria that is macroscopic, progenetic, and actively swims, mimicking a fish prey item.
were collected from a number of fish hosts, including the African sharptooth catfish, Clarias gariepinus (Burchell, 1822), during fish parasitological studies carried out in the Okavango Delta, Botswana.
In Brazil, the parasitic fauna in tilapia is composed by protozoans, monogenoideans, crustaceans and digeneans
with that of the other parasitic flatworms in general and digeneans
in particular in terms of the principal criteria used in the phylogeny of the Platyhelminthes.
