REVIEW ARTICLE Helminths of Antarctic fishes: Life cycle biology, specificity and geographical distribution
Bony fishes (Teleostei) play an important role in the completion of life cycles of helminth parasites in the Antarctica. These fish-es may be definitive, second intermediate or paratenic hosts of the helminths. The most species-rich taxon is Digenea. Virtually all of these digeneans use teleosts as...
