Notes: Sánches et al. (2002) reported adult forms of C. australe from the intestines of a single specimen of bottlenose dolphin T. truncatus . Aznar et al. (2012) suggest that C. australe cannot apparently reproduce, nor even grow, in cetaceans. Therefore, we re-assigned these specimens as juvenile forms of C. australe .
