The whale washed ashore at Khardanda near Uran last evening, the official said, adding that some visitors to the sea shore first spotted it.
"It is likely that this is a blue whale," N Vasudevan, additional principal chief conservator of forest, said.
"We will bury the carcass at the site itself," Vasudevan said.
A 48 feet long whale had washed ashore on the Uran coast in 1978.
