The Unidentified Gigantic Sea Beast Has Mystified the World

49-foot-long slimy carcass of a giant mysterious sea creature has been discovered after it washed up in Maluku on the Indonesian island of Seram.

The sea monster was first spotted by local resident Asrul Tuanakota on Tuesday, according to Beritasatu.com.

Tuanakota, 37, mistook it for a stranded boat in the dark, but quickly discovered it was something much stranger.

The cause of death of the behemoth is still unknown which is thought to have passed away at least three days prior to washing up on the shore.

The beast has become a mystery as its species is still unidentified. The baffled locals are speculating that it might be a giant squid or the remains of a whale. However, Lab tests are underway to confirm the species.

In the meantime, locals have been flocking to Hulung Beach in West Seram to see the mysterious remains.

Earlier this year, a mysterious hairy sea monster was found on a beach in the Philippines.It shocked locals who speculated the two-tonne creature was a kind of rare undiscovered dugong.

It was later identified as a whale - but had developed a strange appearance due to decomposition.
