The mutilated body of the captain of a sunken tanker ship was recovered Sunday, five days after the accident caused a massive oil spill on the Shela river flowing through the Sundarbans mangrove forests.
Captain Mukhlesur Rahman had been missing since Tuesday when the OT Southern Star 7 capsized, Xinhua reported.
Seven crew members aboard the oil tanker had managed to swim to the bank.
A 100 km oil slick was seen floating on the Shela river Sunday, though officials assured that the country's government had strengthened efforts to remove the layer of oil that had seeped into the Sundarbans mangrove forest.
Environmentalists have expressed grave concern over the accident, saying that the plants and aquatic resources of the world's largest mangrove forest, the Sundarbans, would suffer a big blow as a result of the massive oil spill.
The oil spill poses a serious threat to all aquatic creatures, including dolphins, in that part of the river as the amount of oxygen in the water is likely to fall, they warned.
