Acanthocephalan peritonitis (AP; trans-intestinal migration of acanthocephalan parasites into the peritoneal cavity resulting in severe peritonitis), is a common cause of mortality in southern sea otters (). Although spp. acanthocephalans have been implicated in these infections, the species causing AP has been an important unresolved question for decades. We used morphological and molecular techniques to characterize acanthocephalans from the gastrointestinal (GI) tract and peritoneal omentum of eighty necropsied southern sea otters Only was found to have perforated through the intestinal wall and migrated into the peritoneal cavity of examined sea otters, resulting in AP. Morphological and molecular criteria confirmed that was synonymous with A second sp., likely , was present only in the intestinal lumen, did not penetrate through the intestinal wall, and was not associated with AP.
棘头虫性腹膜炎（AP；棘头虫寄生虫经肠道迁移至腹腔导致严重腹膜炎）是南海獭死亡的常见原因。尽管多种棘头虫被认为与这些感染有关，但几十年来，导致AP的物种一直是一个重要的未解决问题。我们使用形态学和分子技术对80只经尸检的南海獭的胃肠道和腹膜网膜中的棘头虫进行了特征描述。仅发现一种棘头虫穿透肠壁并迁移至被检查海獭的腹腔，导致AP。形态学和分子标准证实该种与 同义。另一种棘头虫物种，可能是 ，仅存在于肠腔内，未穿透肠壁，且与AP无关。
