Three whales have washed up dead off the coast of East Anglia, coastguard rescue services have confirmed.
Onlookers were shocked to discover the remains of a gigantic dead sea monster in Harwich, Essex.
The blotchy body found yesterday afternoon turned out to be an adult minke whale - measuring a whopping 40ft in length.
A baby whale was then discovered dead in Orford, Suffolk.
Felixstowe whale rescuers then released a video of a third whale found lifeless.
A spokesman for the UK Coastguard said: "Unfortunately the animal has clearly been dead for some time
"We're keen to make sure the animal is removed humanely and safely and taken for disposal.
"Likelihood is it's died in the sea and made its way to shore.
What's hot
"This is an unusual sight.
"With regards to Felixstowe, this is the largest mammal that we've had wash ashore for some time."
A special company will be called in to help remove the mammoth carcass as it is too big to simply leave rotting on the coast.
The minke whalecalf, possibly from the same group – or 'pod' – as the first, was spotted in the River Ore.
Felixstowe Coast Patrol Rescue Service branded this incident "a very sad day for marine mammals."
A Facebook post from the Patrol Service read: "A marvellous pair - such a loss to the ocean life.
"Such amazing mammals."
Don’t miss
Some theories of what killed the whales have begun to emerge.
The whales could have been struck by ships, confused by wind farms, caught a disease or experienced food or hydration problems.
It's also possible they died of natural causes. Autopsies on the remains are in planning.
John Cresswell, chairman of the voluntary Felixstowe Coast Patrol Rescue Service, said: "This is a really sad day. I have worked as a volunteer coast guard for twenty one years now and never seen anything like it.
"I also believe that the wind turbines would have contributed to this, as whales aren't able to communicate properly when wind turbines are being used."
