Dune's Sandworms Break 7 Laws of Biology (But One Real Creature Doesn't) Part_03

[00:00:00]The real killer is breathing. Every animal needs to deliver oxygen to every cell in its body. Small animals can do this through their skin. Earthworms have no lungs. They just absorb oxygen directly through wet skin. Multiply that animal by a thousand and the math falls apart again. Their inner cells are now so far from the surface that oxygen can't reach them by diffusion alone.

[00:00:24]They suffocate from the inside. Big animals solve this by inventing lungs or gills or hemoglobin to fy oxygen around in blood. All of these take billions of years to evolve. Sandworms have no visible lungs in the films, no gills.

[00:00:41]They live in a desert where Arachus' atmosphere isn't even confirmed to have enough oxygen for humans. They're operating without any oxygen delivery system we can identify at a size that demands the most efficient one ever evolved. Then there's the speed. In Dune 2, a sand worm closes a distance of several kilometers in minutes. Estimated speed 60 km hour underground through compacted sand. The energy required to move 400 m of muscle through resistant sand at that speed is staggering.

[00:01:17]Calculations suggest it would consume more calories per minute than a blue whale consumes in a day. Where is that energy coming from?
