Blue whale HEART to be preserved at museum in Toronto

Blue whale HEART to be preserved at museum in Toronto

It is known as the largest animal on our planet, so it's no wonder that the heart of the blue whale is also record-breaking.

Researchers have retrieved an enormous heart from a blue whale carcass in Newfoundland, and discovered that it weighs a staggering 440lbs (200kg), and is the same size as a Smartcar.

The gigantic heart is on display at the Royal Ontario Museum in Toronto.

HOW PRESERVED THE HEART

1) Researchers fillet the tissue into sections. Once they reach the heart, they sever the blood vessels and push the heart out of the rib cage.

2) The team inserts hoses into two blood vessels and pumps in formaldehyde, which stiffens the muscles and stops decomposition.

3) The heart is soaked in acetone over six months, in which time the acetone replaces all the water in the tissue.

4) Researchers soak the heart in a silicone polymer solution and put it in a vacuum chamber, so the remaining acetone bubbles away.

5) A gaseous curing agent hardens the silicone

The heart was retrieved from a whale carcass that washed up on the shore of Newfoundland in 2014.

The whale was one of nine blue whales that died in the area when they became trapped in ice - an astonishing three percent of the wild population. 

When these 300,000-pound creatures die, they almost always sink.

But in a rare event, two washed up on the shores of Trout River in the province of Newfoundland and Labrador.

Scientists were then able to salvage some of the whale's organs to conduct never-before-done research. 

The heart, which measures 5x4x4ft and pumps out 220 litres of blood per beat, was in such good condition that it was a perfect candidate for preservation using a technique called plastination.

During this process, researchers from the Royal Ontario Museum in Toronto pumped the heart with fomaldehyde, stiffening the muscles as stopping decomposition. 

They then soaked the heart in acetone to remove all the water from the tissue, down to the cellular level.

Next, they had to put it in a synthetic plastic, or polymer, bath.

Lastly, scientists put the whole tank of polymer in a vacuum chamber so that the existing acetone would bubble and boil away.

'Fat is very hard to plastinate,' explained Jacqueline Miller, one of the researchers who worked on the plastination.

The heart remained in this vacuum for more than four months. 

Ms Miller referred to the heart as 'Frankenheart' and compared the unveiling to the birth of a child because of how long the team worked on it.

'We're very, very proud,' she said, adding that the preserved heart could last for as long as 1,000 years. 

In order to remove all the water from the heart to preserve it, researchers placed the heart in an acetone bath - the same chemical used in nail polish remover

After the preservation process, the resulting specimen can be displayed and touched, while not decaying or smelling and retaining most of its properties

The gigantic heart is now being displayed as part of the museum's Out of the Depths: The Blue Whale Story, which runs until September 4th this year.

Eleanor McMahon, Minister of Tourism, Culture and Sport, said: 'The ROM's new Out of the Depths: The Blue Whale Story is a must-see on your list of things to do in Ontario this year.

'Unique experiences like this exhibition attract tourists and build on our province's reputation as a top travel destination, especially as we celebrate our 150th anniversary.

'I'm delighted that the Ontario 1 50 program is supporting this rare experience, helping us all learn a little more about the mysterious blue whale.'
