ResumoAcanthocephalans are helminths with life cycles involving at least two hosts.Apart from intermediate and definitive hosts, their life cycle can also include paratenic hosts.Definitive hosts of Antarctic palaeacanthocephalan species include fishes, birds and marine mammals (Zdzitowiecki 1984a(Zdzitowiecki ,b, 1986(Zdzitowiecki , 1996)).Corynosoma pseudohamanni Zdzitowiecki, 1984 was described by Zdzitowiecki (1984b) from the Weddell seal, Leptonychotes weddellii (lesson) (type host), and four other species of seals in the environs of the south shetland islands, Antarctica.Acanthellae and cystacanths of this species in intermediate hosts (Amphipoda) from Antarctica were found by Hoberg (1986), Zdzitowiecki (2001), Zdzitowiecki and Presler (2001), and laskowski et al. (2010).Fishes of the families Nototheniidae and chaenichthyidae and less frequently also of the Bathydraconidae and Harpagiferidae serve as paratenic hosts of Corynosoma lühe, 1904 species -Zdzitowiecki (1984b,
