Why the Big Blue Organ Controls Our Climate

“Saving the Big Blue Organ” refers to the monumental scientific and logistical effort to extract, preserve, and display the heart of a blue whale—the largest organ of the largest animal known to have ever lived on Earth.

The rare preservation process was triggered in 2014, when a deceased blue whale washed ashore in Newfoundland, Canada. Recognizing a once-in-a-lifetime opportunity to study the undocumented anatomy of this marine giant, a research team spearheaded by Jacqueline Miller from the Royal Ontario Museum (ROM) set out to salvage the massive organ before it decomposed. 🐋 Biological Scale of the Organ

Weight: Nearly 440 pounds (199 kg), making it roughly equal to the weight of a small car.

Dimensions: Measures approximately 5 feet tall by 4 feet wide.

Capacity: Pumps an astonishing 60 gallons (220 liters) of blood with every single heartbeat.

Ventricle Size: The internal chambers are large enough that their contractions could easily fill a standard bathtub. 🧪 The Preservation Process (Plastination)

Saving the heart from rotting required an intricate, multi-step chemical engineering feat:

Stabilization: Technicians initially pumped the organ with thousands of liters of formaldehyde to halt decay and keep the tissue from collapsing under its own massive weight.

Dehydration: The heart was later submerged in a cooling bath of acetone to fully strip the tissue of its water molecules.

Plastination: The organ was shipped across the Atlantic to Gubener Plastinate in Germany. Over several months, experts used a vacuum process to force silicone polymers directly into the cells.

Curing: Once the silicone hardened, it transformed the otherwise fragile muscle tissue into a permanent, odourless, and incredibly durable biological specimen. 🏛️ Where It Is Now

Today, this is the only successfully preserved blue whale heart in the world. It serves as a flagship exhibit at the Royal Ontario Museum in Toronto, offering scientists and public visitors an unparalleled look at the sheer scale and evolutionary engineering of marine biology.
