Elasmobranch populations are globally declining due to intensive fishing pressure, making localized assessments essential for effective conservation and fisheries management. The present study aimed to document the diversity and seasonal occurrence of sharks and rays landed along the Parangipettai coast, Tamil Nadu. Sampling was conducted at the Mudasal Odai fish landing centre from June 2023 to April 2024, covering four seasons: summer, pre-monsoon, monsoon, and post-monsoon. Species identification was carried out using standard taxonomic keys and reference databases. A total of 17 elasmobranch species belonging to sharks and rays were recorded during the study period. Post-monsoon landings showed the highest species occurrence, followed by monsoon, pre-monsoon, and summer. Family-wise analysis indicated dominance of Dasyatidae, followed by Carcharhinidae, while Gymnuridae showed minimal representation. Comparison with earlier studies revealed the addition of four species newly recorded from the study area. The findings provide updated baseline information on elasmobranch diversity in the Parangipettai region and contribute valuable data for regional biodiversity documentation, conservation planning, and sustainable fisheries management.
