  Wow, nature is so unique and interesting! By the way, please never show me this picture again!

    do you think they can taste their brain?

      Well, definitely not considering the entire skull sitting in the way.

  I’ve seen that image many times before, but not really stopped to think about the details.

  • ‘Tongue bones’ disturbs me. Doubly so when they seem to be shown curving around the inside of the skull. Are they actually bones, or more akin to tendons?

  • A woodpeckers tongue appears to be bifurcated at the back. I suppose that makes sense if it curves upwards rather than down the throat, but still; nature is weird.

  • 1000G is a lot of force. Even if the brain is padded by the tongue (it’s like they’re almost licking their own brains), the bulk of the brain is still getting bounced around. I wonder if we can learn anything about mitigating TBIs from them?

    Just making sure you understood ‘g’ here is grams (so 1 kg or 9.8 N) and not 1000 G as in the force of gravity (which would be 9800 N / kg).

      If you check other sources as well, it seems to, in fact, be 1000 times gravity. For example check The Audubon Society where it’s quoted as ‘1500 g-force’ units, compared to about 5 on a rollercoaster, this paper which seems to show it as even greater in figure 2 or The Zooilogical Society of London which cites 10000 m/s/s or around 1000 g.

      Interestingly, as woodpecker brains apparently weight about 2.5 grams, the difference between 9.8N of force and 1000 g=0.00259.811000=24.525N isn’t all that great. From reading around it seems their skulls and tongues don’t even absorb much impact. as it’d make their digging less efficient, tgeir brains are just light enough and structured so they don’t get damaged.

    Never before have I considered the idea of “licking their own brains” and I thank you for bringing that thought into my life.

  For the Americans, 1000g is about four sausages

  • HeyThisIsntTheYMCA@lemmy.world ⁨11⁩ ⁨months⁩ ago

    How many snausages is that?

    source

    • runeko@programming.dev ⁨11⁩ ⁨months⁩ ago

      Multiply by 7 for dog sausages.

    For central europeans, it’s about 10 pieces of schocko, 2 large pieces of cheese or 2 pint of beer.

      Central Europe and pint don’t mix well.

  Only 1000g of force? surely it must be more

  source

  • Wizard_Pope@lemmy.world ⁨11⁩ ⁨months⁩ ago

    Moght be 1000G bit that seems excessive

    source

    • MossyFeathers@pawb.social ⁨11⁩ ⁨months⁩ ago

      I looked it up, it’s actually in excess of 1,000G, which is kinda fucking insane.

    • PotatoesFall@discuss.tchncs.de ⁨11⁩ ⁨months⁩ ago

      I suppose the head is probably quite light and 1000g is actually a lot. G’s as a unit would be more helpful here
