The 45-foot long marine mammal might have died some 15 days ago in the deep sea
A large-sized dead whale washed up on Kuakata beach under Kalapara upazila of Patuakhali.
The whale was found on Saturday morning.
Locals suspect that the 45-foot long marine mammal might have died some 15 days ago in the deep sea.
Farhana Akhter of Wildlife Conservation Society said it is a Bryde's whale or Baleen Whale, which has no teeth.
The Bryde's whales eat small fishes and prawns, she added.
She said the Bryde's whale is usually black or grey in color and it could be around 40 to 50 foot long.
These whales are mostly seen in Swatch of no Ground marine protected area of Bangladesh, Farhana said.
Md Kamrul Islam, Kalapara upazila fisheries officer, said the beach management committee will take necessary steps regarding the dead whale.
