A blue whale that washed up in Newfoundland in 2014 was in good enough condition that mammalogy technicians could preserve its 440-pound ticker. Here's how they did it. (From 2017)
Starting at the tail, 10 workers pull back strips of flesh with a hook and fillet the blubber and tissue into sections. Once they reach the heart, technicians sever the blood vessels; then they cut open the pericardial sac around the heart and push it out of the rib cage. The team is now knee-deep in decomposing guts. “It was like mud wrestling,” Miller says.Without blood, the heart flattens. So researchers insert hoses into two blood vessels and cork the rest with plungersand plastic bottles.
Technicians triple-wrap the wet organ in absorbent mats, forklift it into a padded steel tank, and dump in thousands of packing peanuts. Then the heart gets flown to Gubener Plastinate in Germany—the place that does the human displays for Body Worlds exhibitions.German anatomists soak the heart in acetone, constantly changing out the fluid. Over six months, the acetone replaces all the water molecules in the tissue. Then the magic of plastination happens.
