You're Not Hallucinating. That's Just Squid Skin. | Deep Look

  • Publicado el 8 sep 2015
  • Octopuses and cuttlefish are masters of underwater camouflage, blending in seamlessly against a rock or coral. But squid have to hide in the open ocean, mimicking the subtle interplay of light, water, and waves. How do they do it? (And it is NOT OCTOPI)

    --- How do squid change color?
    For an animal with such a humble name, market squid have a spectacularly hypnotic appearance. Streaks and waves of color flicker and radiate across their skin. Other creatures may posses the ability to change color, but squid and their relatives are without equal when it comes to controlling their appearance and new research may illuminate how they do it.
    To control the color of their skin, cephalopods use tiny organs in their skin called chromatophores. Each tiny chromatophore is basically a sac filled with pigment. Minute muscles tug on the sac, spreading it wide and exposing the colored pigment to any light hitting the skin. When the muscles relax, the colored areas shrink back into tiny spots.
    --- Why do squid change color?
    Octopuses, cuttlefish and squid belong to a class of animals referred to as cephalopods. These animals, widely regarded as the most intelligent of the invertebrates, use their color change abilities for both camouflage and communication. Their ability to hide is critical to their survival since, with the exception of the nautiluses, these squishy and often delicious animals live without the protection of protective external shells.
    But squid often live in the open ocean. How do you blend in when there's nothing -- except water -- to blend into? They do it by changing the way light bounces off their their skin -- actually adjust how iridescent their skin is using light reflecting cells called iridophores. They can mimic the way sunlight filters down from the surface. Hide in plain sight.
    Iridophores make structural color, which means they reflect certain wavelengths of light because of their shape. Most familiar instances of structural color in nature (peacock feathers, mother of pearl) are constant-they may shimmer when you change your viewing angle, but they don't shift from pink to blue.

    My involuntary breathing ability has a 16-hour cooldown and I can only activate it when my character is offline, and I can't find it on the normal tech-tree for the online abilities, and it was an option when I first made my character for the idle part of the tech-tree for The Outside.

      If you don't care for cephalopods - totally get that. But 'octopuses' is the most correct term. Some like to say 'octopi' but that would be adding a Latin suffix to a Greek word.

      Not so. It's a latin vs. greek root kind of thing - Octopuses is more technically correct and is the term scientists use. But Octopi has entered popular use and considered acceptable.

      It’s not just you - but ‘octopuses’ is technically more correct. ‘Octopi’ sounds nice, but would only make sense if the origin of the word was Greek. Alas, ‘octopus’ is rooted in Latin. All that said, both are acceptable in common usage.

    Incorrect.....this is a prime example of neuro-conduction, and just how amazing neuro-transmission really is. Basically, the squid had its nerve cut.....Lashley (Karl), a neuro-scientist taught us that the brain can reform neuro connections AFTER trauma. This is an example of such neuro formations, and reformations, based on necessity. The squid's brain forms alternate routes for ways to get the spots to begin to start showing again....the same thing happens in the human brain, post trauma...
