The genus comprises hematophagous parasites of marine aquatic species, including cephalopods, marine mammals, and pelagic fish. Nine species have been officially included in the genus plus another six . They are most often found in the host's musculature, without penetrating internal organs. For the present study, 83 hearts from swordfish () caught in the Mediterranean Sea were sampled and immediately fixed in formalin for histopathological analysis. In total, 10 (12.05%) hearts were found to be parasitized by copepods of the genus . Macroscopically, there was mild-to-severe fibrinous pericarditis with atrial wall thickening and multiple parasitic nodules. Histologically, the parasitic nodules were surrounded by an inflammatory-necrotizing reaction. Parasitic infestation by spp. is common in pelagic fish and in swordfish, in particular. Here, however, we report atypical cardiac localization. A future area of focus is the evaluation of cardiac spp. infestation by histopathology and genetic identification of the parasites.
该属包括海洋水生生物的吸血寄生虫，其中有头足类动物、海洋哺乳动物和远洋鱼类。该属已正式收录9个物种，另有6个物种。它们最常出现在宿主的肌肉组织中，而不穿透内部器官。在本研究中，对在地中海捕获的83条剑鱼（）的心脏进行了采样，并立即用福尔马林固定以进行组织病理学分析。总共发现10颗（12.05%）心脏被该属的桡足类寄生虫寄生。肉眼可见，有轻度至重度的纤维素性心包炎，伴有心房壁增厚和多个寄生结节。组织学上，寄生结节被炎症坏死反应所包围。该属物种的寄生在远洋鱼类尤其是剑鱼中很常见。然而，在此我们报告了非典型的心脏定位。未来的一个重点领域是通过组织病理学和寄生虫的基因鉴定来评估心脏该属物种的感染情况。
