Abstract

Carcasses of dugongs (Dugong dugon), beached along the coast of Tamil Nadu, India between February 2021 and September 2023 were examined for the presence of helminth parasites. The nematode Paradujardinia halicoris was found in four out of the six carcasses examined, with a range of about 20-45 worms in each. The worms were identified based on the morphological features viz., anterior mouth parts (well developed lips, separated by a transverse groove on the oral surface), genital structures in male (alate spicules with rounded ends) and female worms. The gross and histopathological changes in the carcasses were discussed.
