    Sponges might not look like particularly complex animals, but they've had billions of years to evolve their own special systems. And one of those systems might involve sending messages through their body in the form of light.

      I’ve had dreams where I could shapeshifter, I did it by moving cells and tissues around, I remember wishing I could set states and turn into specific shapes like a switch, didn’t happen though. I get lots of dreams about either shapeshifting, being incorporeal, or not human, sometimes being stuck in someone else’s body.
      I guess my point is is having to think about where to move your cells sounds mentally exhausting

    The crazy thing about a light-based nervous system is that you can theoretically pack a lot more complexity into a small space than with an electrical one. Two light rays can pass through each other without interfering, so you can have multiple light "wires" facing different directions through the same space, while wires would have to navigate around each other.

      Wouldn’t this depend upon the wavelengths created by the bioluminescence? Most such light in the ocean tends to be blue. I suspect that this is due to how light interacts with water. Perhaps under different gravity, these interactions are different?
      Also, suppose that, instead of water, life develops in oceans of methane? These frozen worlds tend to be farther from the star, and have less light in the environment. Bioluminescence might be critical to the development of animal life in such an ecosystem.
      There are very interesting possibilities here.

      To be fair, sponges are only known to have existed for around 800 million years, though the first well-preserved fossil sponges (based on what I've read) seem to be only around 580 million years old. And it is likely that the electrical central nervous system we're familiar with evolved prior to the Cambrian Explosion over 540 million years ago, since most of the animals that existed at that time already had it.
      It would be cool if we could figure out from the ancient fossil sponges that they had this "optical" nervous system all the way back then!

      Organs have distinct boundaries that allow them to be physically independent of each other... Your stomach and your liver are both right next to each other, serve a common system (digestive), and are completely and readily separated from each other.
      The structure within the sponge is more like the brain (only less the thinking part lol) - groups of cells that are all "the same" but doing different things depending where they are located within the brain, and these areas are not succinct and cannot be separated from each other as modular units the way the liver and stomach can.

    I remember hearing part of a conversation, back when I was a young teen about how certain things in the deep ocean may have come from silicon.
    That was the last I heard of it, and I stopped brining what I heard up, decades ago.
    After awhile, I figured I must have confused something that I didn’t understand. I guess I did, however, I probably heard some college kids talking about, or just me not understanding what I had heard, what was a lifetime ago.
    This was likely the root of my “Silicon based life” story, from all that time ago… It was never about deep sea critters evolving from silicone but, maybe a passing conversation about deep sea sponges using it to do something.
    This, I think, happened around 02, or 03 so the timeframe seems to work. I do feel like an old, confused, childhood memory just got an answer after all these years.

    I have a strange theory about what we typically call primitive organisms. It goes along the lines of they evolved first, so were capable of occupying niches where they didn't need a lot of complexity to survive. As evolution progressed these niches became filled. That forced later organisms to develop more complex forms just to survive. Kind of reverses the thinking that the more complex forms are "superior" to the more "primitive" life forms. Just a different way of looking at the same picture.

    You make it sound like all sponges would do this, and reinforce that impression by showing images of many different kinds of sponges. But obviously this would only apply to those sponges that have silica as their basic structures. That would be a definite minority.

    If sponges use light to process their environment and to react to it, it makes the choking out of our reefs by glitters even more grim 😢

      You might have missed the idea that they are *producing* the light they are using. This changes things. Kinda like you being able to turn on your phone's flashlight in the dark. Doesn't matter that the sun isn't up.
