This Giant Dead Sea Creature Washed Up On An Island, And It's Freaking Everyone Out

Images posted online of an enormous carcass that washed up on the shore of an Indonesian island are captivating people across the world.

The Jakarta Globe calls the massive, rotting body a giant squid, and reports that a resident of Seram Island discovered the 49-foot dead creature on Tuesday.

But two marine experts told HuffPost that the animal actually appears to be some sort of baleen whale.

"Giant squid are invertebrates and there are clearly bones visible (jaw, skull, vertebrate) so I am very comfortable saying it's some type of rorqual whale," said Regina Asmutis-Silvia, executive director of Whale and Dolphin Conservation.

"Certain species of baleen whales (rorquals) have 'ventral grooves' which run from their chin to their belly button. It is stretchy tissue that expands when they feed," she added.

She identified these grooves in images and also included photos in which she pointed to what she believes are the whale's jaw bone and skull.

Edith Widder, CEO and senior scientist at the Ocean Research & Conservation Association, said it was difficult to determine from images alone but that some photos show what looks like baleen plates.

"My guess is it's a baleen whale," she said.

Footage from the scene shows the decaying body turning the water around it a deep red.
