Whale lice (Isocyamus delphinii) on a harbour porpoise (Phocoena phocoena) from German waters

“…The geographical distribution of I delphinii is reported to be approximately between 70°N and 60°S (Bowman 1955, Gruner 1975, Stock 1973a, 1977, Greenwood and others 1979, Raga and others 1983, so its occurrence in this case seems well within the normal range. Rappé (1990) suggested that the lack of records of I delphinii from the North Sea could be attributed to this cyamid's preference for oceanic and warm temperate host species/populations, and that cetacean populations in the North Sea were free of cyamids until incursions of infected groups of animals occurred in the 1960s.…”

The host-specific whale louse (Cyamus boopis) as a potential tool for interpreting humpback whale (Megaptera novaeangliae) migratory routes

“…The whale lice constitute the entire family Cyamidae Rafinesque, 1815, that comprise 28 species within eight genera, where Cyamus Latreille, 1796 is the most speciose genus, and the majority of species within Cyamus are parasites of see whales (Iwasa-Arai and Serejo, 2018). Cyamus boopisLütken, 1870 is the only species found living on humpback whales, and it has been recorded from M. novaeangliae all over the world (Lütken, 1870;Hurley, 1952;Margolis, 1955;Gruner, 1975;Fransen and Smeenk, 1991;Rowntree, 1996;Abollo et al, 1998;De Pina and Giuffra, 2003;Iwasa-Arai et al, 2017a,b).…”
