They move heat via blood into their bones such that their bones sheild the heat and can be re-pumpted back into the muscles over time to allow for deep divings.

- xattt 3y agoI have a crazy suspicion this mechanism is a thing in humans. After cold weather sets in the fall, it takes me a day or two before I start to be bothered by the chill. Mid-winter, I start to crave saunas. My assumption is the skeleton, marrow and body fat (or some other body structure with high thermal mass) act as a heatsink that expels some built up heat.
- samstave 3y agoMaybe this is where "I can feel it in my bones" comes in
- dotancohen 3y agoBones? I thought that sharks have no bones.
- samstave 3y agoI wonder if cartilege vs bones are a better heat / oxygen moderating permeable filter/exchanger, thus no bones....
- samstave 3y agoOK this is going to be a crazy post, just hold your horses cartelige is a permeable material for various occupants, oxigen being one. So we find that highly oxigenated creatures are larger and more carnivorous we also know that high ingestion of oxygen results in larger creatures so if a shark has a larger ability to permeate oxygen into the muscles and have the ability to store heat, plus the ability to transfer heat/oxy btwn bodies... This is why we can see a body +500 years old.. buoyed by the buoyancy of less dense bones, such as cartilage.
