Aspects of Ecology and Biogeography of Acanthocephala on Antarctic Seabirds [Données écologiques et biogéographiques sur les Acantocéphales d’Oiseaux marins antarctiques]
Four species of acanthocephalans are reported from seabirds, nototheniid fishes and gammaridean amphipods in the western Antarctic. Corynosoma hamanni (von Linstow, 1892) was found in Phalacrocorax atriceps King, Chionis alba (Gmelin), Larus dominicanus Lichtenstein, and Catharacta lonnbergi (Mathew...
