Around fifty carcasses of jellyfish washed ashore along different points of Cox's Bazar beach on Sunday morning.
These dead jellyfish have been washed ashore by the tidal water throughout Sunday from Labani point to Sugandha point of the beach.
Around 50 small and large jellyfish carcasses were found stuck in the sand at various points of the beach.
But no one could tell the reasons behind this huge number of dead jellyfish turning up
Abdur Sukkur, a fisherman in the Himchari area, said that it's very unusual for so many jellyfish to die at a time.
Deepak Sharma Dipu, president of Cox's Bazar Forest and Environment Conservation Council, said it is important to investigate the reason behind the sudden death of so many jellyfishes.
These jellyfish might have come close to the shore and got caught in the fishermen's nets. Later, the carcasses started washing up on the beach as the fishers threw those away, said Abu Syed Muhammad Sharif, head of the Biological Oceanographic Division of the Council.
He said that if people come in contact with dead jellyfish lying on the beach, it can cause various problems, including itching.
Jellyfish can still emit toxins when dead or broken apart.
General Secretary of Cox's Bazar Fishing Boat Owners Association Delwar Hossain said that there was no report of jellyfish being caught in any trawler's net.
Although rare, this is the second such occurrence in the space of a month. Earlier on August 4, it was reported in the media that almost 100 such jellyfish carcasses had washed up on Cox's Bazar beach in one day.
