Much like the blue whale, the heart of the blue whale is also record-breaking big.
And researchers have now retrieved an enormous heart from a blue whale carcass in Newfoundland and discovered that it weighs a whopping 200 kgs! It is the same size as that of a smart car.
The gigantic heart is on display at the Royal Ontario Museum in Toronto.
The heart was retrieved from a whale carcass that washed up on the shore of Newfoundland in 2014.
The whale was one of nine that died there while getting trapped in ice.
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.
Researchers pumped the heart with formaldehyde thus stiffening the muscles and stopping decomposition of the whale heart.
