Blue whales are the world's largest animals, and they weigh up to 137,000kg, but many people cannot believe that they have huge hearts. 

Researchers in Toronto, Canada, have preserved a huge, 200kg blue whale heart that was retrieved from a carcass in Newfoundland in 2014. 

The gigantic heart which has the same size as a smart car pumps up to 220 litres of blood per minute. The whale's heart has been placed on display at the Royal Ontario Museum.

According to the Toronto researchers, they are preserving it through a process of plastination, which involves soaking it in acetone to remove all the water. 

The researchers also pumped it with formaldehyde, which stops decay by stiffening the hearts muscles. They then drained it of acetone and placed it in a vacuum for over four months.

One of the researchers, Jacqueline Miller, said the preserved heart could last up to 1,000 years.
