Distribution:

Nematodes of the genus Peritrachelius (Anisakidae) are parasites of marine organisms. The life cycle of these nematodes requires marine mammals, mainly cetaceans, as the definitive hosts, and crustaceans, fish, and cephalopods as intermediate or paratenic hosts (Klimpel and Palm, 2011; Safonova et al., 2021).

Feeding:

Biology and Ecology:

Humans are accidental hosts due to ingestion of raw or undercooked fish containing the third infective-stage larvae. Human anisakiasis patients suffer from abdominal pain, nausea, vomiting, and/or diarrhea (Dorny et al., 2009).
