Parasite infections (Trematoda, Digenea) of Sagitta friderici (Chaetognatha) from the southwestern Atlantic Ocean: Prevalence and distribution

The following chaetognaths were found in the Atlantic Ocean between 34 to 40° S and 52° 20' to 62° 00' W: Sagitta friderici, S. tasmanica, S. minima, S. gazellae, and S. enflata (in order of abundance). Of these, only S. friderici was parasitised by unencysted metacercariae of the families...
