Acanthocephalus lucii is one of the most widely distributed species of acanthocephalans infecting marine fishes throughout India. Adult worm of Acanthocephalus lucii were collected from small intestine of Caranx ignobilis from Nagapattinam. They have group of acanthocephalan adhering in the host gut. Acanthocephalus lucii proboscis through the infected fish intestine about 0.7-1.4 mm deep. Maximum 12 Acanthocephalus lucii were collected from the single infected host. Totally 4476 fishes were examined which is out of 2648 host were infected with acanthocephala parasite. Morphology of the worms was cylindrical structure, proboscis hooks were uniformly arranged and smallest posterior end. Length of the Acanthocephalus lucii was up to 2.8 - 6.3 cm and weight was up to 0.012-0.068 g. Higher prevalence (63.84 %), intensity (10.01 %) and abundance (6.39) were observed at post monsoon season. The current study was carried out an occurrence, description of the parasite, prevalence, mean intensity and mean abundance was observed.
