在智利海岸，鲨鱼和鳐鱼是研究最少的鱼类之一，因此关于它们寄生虫的定量数据很少或几乎不存在。2014年3月和4月期间，在OCELIA号巡航船上捕获的Prionace glauca（n= 12）和Isurus oxyrinchus（n= 1）的身体沿着不同部位采集桡足类寄生虫。经鉴定，熊猫科有3种：Echthrogaleus coleoptratus、Dinemoura producta和Nessipus orientalis。后一种是在智利沃茨首次记录。这些桡足类没有表现出感染部位的偏好沿着寄主身体。考虑到这些寄生虫种所描述的宿主范围广泛，可以得出结论，它们是广泛地理分布的通才寄生虫。
In the Chilean coast, sharks and rays are one of the least studied fish groups, therefore quantitative data about theirparasites are scarce or almost non existing. Copepod parasites were collected from different sites along corporal body of Prionace glauca (n= 12) and of Isurus oxyrinchus (n= 1) captured onboard cruise OCEARCH during March and April 2014. Three species belonging to the Pandaridae family were identified: Echthrogaleus coleoptratus, Dinemoura producta and Nessipus orientalis. The latter species is here recorded for the first time in Chilean waters. These copepods did not show infection site preferences along host body. Considering the wide range of hosts described for these parasite species, it is concluded they are generalist parasites of wide geographic distribution.
