"The dolphin died a few days ago. Its body has started decomposing. There were no signs of injury on the body. Therefore, we have mentioned old age as the cause of death in the autopsy report," Dr Manzurul Kibriatold The Business Standard.
He noted that the age of the dead dolphin could not be determined immediately.
"The dolphin has been buried. We will collect its bones after six to seven months for examination, which will then allow us to determine its age. Typically, a dolphin can live for fifteen to twenty years," he added.

Locals retrieved it and brought it to the riverbank. Upon receiving the news, researchers from the Halda River Research Laboratory of Chittagong University arrived at the scene, conducted an autopsy, and buried the dolphin.
