Thirty-one South American sea lion pups found dead in Punta León, Argentina, during the summer of 2002, were examined for hookworms, and no apparent trend between body condition and intensity of hookworms was observed.

Examining several poorly known cetaceans of Argentina found poor parasite-species assemblages are consistent in marine mammals of Patagonia, and the limited parasitological information gathered is valuable for conservation or management of these hosts in PatagonIA.

Worms were most similar to specimens collected in other South American localities, however, 1 male had 2 spines adjacent to the genital pore and isolated from the rest of body spines, confirming the recent reassignment of C. cetaceum to Corynosoma.

The stomachs and intestines of 9 Commerson's dolphins incidentally caught in trawl nets in central Patagonia and 23 stranded on beaches in Tierra del Fuego were surveyed for helminth parasites, suggesting some differences in habitat use, diet and sex between Commerson’s dolphin populations in the 2 study areas.

It is suggested that potential prey are probably important in parasite transmission in this and other dolphins from the Patagonian region and is consistent with parasite assemblages of other cetaceans off Patagonia.

The present study provides the first descriptions of cestodes from M. hectori and P. dioptrica, thus enriching the knowledge regarding the helminths of insufficiently studied marine mammals.
