Anisakis

Anisakis sp.

Host: Lagenorhynchus obscurus (Gray)

Site in host: intestine, stomach

Developmental stage: N/A

Locality: Playa Bonita (43º21'S, 65º03'W), Chubut province

References: Loizaga de Castro et al. (2014)

Notes: Loizaga de Castro et al. (2014) identified these nematodes as Anisakis sp. Type II sensu Berland (1961) from the stomach and intestine of the dusky dolphin L. obscurus. The morphology of the larval Anisakis Type II is shared by three different species: A. brevispiculata Dollfus, 1966, A. physeteris, and A. paggiae Mattiucci, Nascetti, Dailey, Webb, Barros, Cianchi & Bullini, 2005, which parasitize strictly whales of the family Physeteridae, i.e. sperm whale, pygmy sperm whale and dwarf sperm whale (see Mattiucci and Nascetti 2008). Therefore, the identification of these nematodes by Loizaga de Castro et al. (2014) seems to be doubtful.
