    Hypothetically, how many penguins would one have to sneak out of the zoo in order to fashion themselves a penguin 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. Air 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 compressible, so seals don’t suffer the same problem.

        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?

          Yes.

          Ocean water can also be supercritical. You can find videos on youtube of under-ice water flash-freezing out from a nucleation site.

      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

          Yes, but as much as I despise people wearing dead animals, I also don’t think it’s that awful to see something like that in a scientific context on the internet.

            This isn’t a scientific context it’s a social media site :/ and I’m not asking them not to post it or cancelling them for it - I’m asking that they slap a nsfw tag on it or a content warning or something

              For me NSFW is something that can get me fired if somebody sees it on my screen during working hours or something that can put the consumer of the content at risk, like gore images making hemophobic people faint. I can see how this image can be a bit disturbing, but I don’t think a piece of leather should be censored, as it dilutes the meaning for the tag too much.

              I’d then click on something NSFW thinking there is just another piece of leather with feathers under the tag… I don’t think I need to explain this one.

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

      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.
