(via Smithsonian) The Royal Ontario Museum (ROM) in Toronto, the first museum in the world to display a fully intact, preserved blue whale heart… the largest mammal on the planet. Although the project would take a full three years from start to finish, the museum knew that putting the heart on display would be an indispensable way for the public to see one up close and understand the sheer magnitude of the animal.
