A 35-foot-long whale calf that was rescued and pushed back into the sea after a 40-hour-long operation has died due to complications and got washed ashore at Ganpatipule in Ratnagiri.

"After sending the whale calf, weighing nearly 4 tons, into the deep sea on Wednesday, it was alive and swimming on its own. But later, it might have developed health-related complications which led to its death," Deputy Forest Officer Girija Desai told PTI.
