Abstract

During the routine jelly plankton survey along the Mandapam coastal waters, a swarm of hydrozoans was collected in February 2022. These were identified as the immortal jellyfish Turritopsis cf. dohrnii. The hydrozoan jellyfish swarm is the medusa stage of the organism, whereas the larval phase is sedentary and attached to some hard substratum at the bottom. Once a larva metamorphoses into a polyp, it buds off as a jellyfish, causing a bloom.
