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