A new brachycladiid species (Digenea) from Gervais’ beaked whale Mesoplodon europaeus in north-western Atlantic waters
Abstract A new species of the digenean family Brachycladiidae Odhner, 1905 is described from the bile ducts of a Gervais’ beaked whale Mesoplodon europaeus Gervais (Ziphiidae) stranded on the North Atlantic coast of Florida. These parasites were assigned to Brachycladium Looss, 1899 and differed fro...
