Feather coat!

  I knew they were birds so of course they have feathers but for some reasons I thought they would look more like seals with lots of fat.

    They have that too, but less of it.

    The feathers work almost like a dry suit. Trapping a layer of air to insulate their bodies and keep them exceptionally warm, even as they swim into water that’s below freezing temps.

    They can’t dive as deep though, as their insulation is partly provided by air. Ai is compressibly by the quickly increasing water pressure, so the cold will sap their body heat faster as a penguin dives deeper.

    Fat isn’t compressibly, so seals don’t suffer the same problem.

      Fat isn’t compressible

      If the water is bellow freezing temps wouldn’t that mean that the water is ice? Or can it go bellow freezing in the ocean because of the salt?

  Did they hurt the penguin to get that sample?

    His condition is stable

      Death is the most stable condition.

    This is a very old sample of penguin skin in a museum. But to answer your question, yes, they killed the bird.

      Not before torturing first. How else would he give up his insulating secrets.

    It died peacefully after a life that was longer and happier than average, surrounded by loved ones, and having come to terms with its mortality beforehand.

  Can we like, nsfw tag images of splayed out penguin skin?

  source

  • TwilightKiddy@programming.dev ⁨7⁩ ⁨hours⁩ ago

    Well, it looks more like leather and as terrible as this practice is, society very much encourages displaying leather.

      Just because something is normalised doesn’t mean it should be, or that we don’t have the capacity to do things differently or more compassionately :3

  Is it going to be OK?

  • turtlesareneat@piefed.ca ⁨12⁩ ⁨hours⁩ ago

    Yes they just borrowed its skin for a while, it was happy to be involved

  So the black coat is actually fluffy?

  It would be interesting to know their internal temperature at -60°C ambient.

    I bet the locals will give you looks coming all the way to Antarctica to put thermocouples up penguin butts, but hey, science.

    • trxxruraxvr@lemmy.world ⁨10⁩ ⁨hours⁩ ago

      The locals on Antarctica are all scientists. I’m sure they would understand.

  So do we have extreme weather gear based on similar principles and layout, or have we discovered a configuration that works better?

  • autriyo@feddit.org ⁨6⁩ ⁨hours⁩ ago

    Most wearable insulation works pretty similar, right?

    Its a layer of air, trapped in some kind of matrix, so that it can’t move, with some sort of inner and outer shell.

    I think it would be too fragile for most purposes. Unless you can make missing feathers grow back like a living penguin it would wear out quite fast.

    Not yet but hopefully soon because penguin coats are really expensive.
