New host copepod for the epizoic diatom Protoraphis atlantica from the coastal waters of the Bay of Bengal
摘要
The epibiotic relationship between the calanoid copepod Pontella securifer and the pennate diatom Protoraphis atlantica was reported from the coastal waters of the southwestern Bay of Bengal. The epizoic diatom was attached to the caudal rami and geniculated antennae of the neustonic copepod Pontella securifer. Epibiosis was observed on the male host from the coastal waters of Northern Tamil Nadu (Ennore) during the southwest monsoon (August 2023). The present study provides the first evidence of Pontella securifer being a host to Protoraphis atlantica and the first record of Protoraphis atlantica from the Bay of Bengal, Northern Indian Ocean.
