Around 40 dolphins have been found dead in mysterious circumstances in Mauritius oil spill area. According to Reuters, on Friday, environmentalist Reuben Pillay was alerted by residents who had ventured out in a boat that a mother dolphin was swimming around her dying baby. While the baby had died by the time he reached, the mother initially looked quite normal.

However, soon, “she swam in circles in front of the boat, she moved her tail very violently and after about five minutes she just stopped moving, and she sunk … We heard cries, I thought it was a woman on the boat – but they told me, no – it was the dolphin. We didn’t know what to do. It was heartwrenching,” he said.

According to the Mauritius fisheries ministry, 38 carcasses had washed up on the beaches so far.

The autopsy reports of 25 dolphins are expected to come in the next few days. Two dolphins who have been examined by veterinarians had no trace of hydrocarbons in their bodies. As per preliminary autopsy results, they had signs of injury

News of dolphins dying in an area hit by an oil spill has been the cause of concern of environmentalists all around the globe. The oil spill was caused by a Japanese ship, the MV Wakashio, which struck a coral reef last month.

Greenpeace, on Thursday, called on Mauritius government to launch an “urgent investigation to determine the cause of the deaths and any ties to the Wakashio oil spill”.
