Occurrence of Anisakis spp. (Nematoda: Anisakidae) in a pygmy sperm whale Kogia breviceps (Cetacea: Kogiidae) in Australian waters

Little is known about parasitism in the pygmy sperm whale Kogia breviceps. Here, the occurrence of 3 anisakid species in a female pygmy sperm whale found stranded at Baxter's Beach, Australia, is reported, along with histopathological findings from this whale. Thirty-nine nematodes were submitt...
