So I built a stegosaurus model kit, which included some factoids in the instructions. One of these factoids was that stegosaurs are not believed to have had a secondary brain in the hips to help them control their rear half after all. That was wild to me, since the whole stegosaurs and sauropods with their tiny heads needing a secondary brain for their huge bodies was commonly accepted back when I was a kid. So I looked it up, and indeed, the current hypothesis is that the cavity that the second brain was thought to occupy is used for a thing called a glycogen body. But what exactly does a glycogen body do? We’ll get back to you on that, apparently.

    And could still be true.

    Edit: See my later comment on more sources on bones. Fr guys, I have no idea either way, but if you’re going to say my source is full of shit, provide your own legit sources to back you up.

    Edit 2: If you continue down this thread, there’s a lot of trolling going on. This could be for 2 purposes, make me look like an unreliable source (on biology, that might be true) and ruin the vibe.

      I can’t speak for every creature in this source but practically everything it says about turtles is a straight fabrication. They have one brain. It’s oddly shaped but just one. Next, it’s in their skull, not their neck - that’s crazy. Finally, TURTLES HAVE BONES WTF

      What the fuck is that article? It’s absolute nonsense. Like a first gen AI was trained on a single biology textbook.

      The mosquito brain has three main parts: the antennae, the maxillary palps, and the proboscis.

      Octopuses don’t have any real social structure like mammals do. Instead, they communicate through chemical signals. But these chemicals can transmit emotions just as effectively as words and they have two eyes.

      Animals with multiple brains include octopuses, cephalopods (squid), and even humans.

      The brain of a cuttlefish is located in the head, which is made up of two parts: the upper part contains the eyes, and the lower part contains the mouth.

      Cuttlefish is one of the smartest animals in the world. They are able to solve complex mathematical equations

        You didn’t know that cuttlefish can derive non-trivial solutions of the Einstein field equations? They can solve all ten at once because they have ten brains.

          The entire website is like that. Except nearly every article is

          "These are the only 27 animals that have blue eyes!

          Humans are the only species with blue eyes

          Other species with blue eyes include the Siberian Huskie, the Great Dane, and the Dalmatian

      I mean, yes, but… What other vertebrates have developed a secondary brain? That’s a big deal evolutionarily, considering all other vertebrates have the one.

            No idea who you are talking about, but it’s well known that we have a really large and complex neuron structure spread through our digestive system.

            Nobody calls it a brain just because it’s not an organ.

              There is SO MUCH to unpack on this subject. We’re just now figuring out how our gut biome influences the rest of our body and mind, as if those are separate things. :)

        Turtles have two brains. The first brain is located in the head and controls the eyes, ears, mouth, and other senses. The second brain is located in the neck region and controls the legs, tail, and other body parts.

        The brain of a turtle is much like ours, except for one big difference: they don’t have any bones. Their skulls are made up of cartilage instead of bone. This means that their skulls are flexible and can change shape to adapt to different situations.

        Edit:

        Source 2:

        Turtles possess a unique protective shell, leading to questions about its nature. In fact, turtles do have bones, and their shell is an integral, living component of their skeletal system, not a separate structure they can leave. This remarkable shell provides comprehensive protection, housing all their internal organs.

        Looks like turtles have bones and you all flunked biology class. I didn’t flunk, but I didn’t pass with flying colors, so I have no idea on any of this shit.

            This isn’t true, the other poster’s source is likely AI generated. Turtles certainly have unique brain structures, but it’s still considered one brain with multiple regions. And these regions are all within the skull, not the neck.

            EDIT: Just read their source again and they state turtles don’t have bones. Wow.

              It gets better. Apparently, we all have multiple brains.

              It says leeches have 32 brains, pea sized, with 400 neurons, and 500 different types of neurons. Yeah, that’s clearly bullshit.

            Sorry about that, I edited it in. I’m a little in shock that there are animals that have more than one brain.

      make me look like an unreliable source (on biology, that might be true)

      On what topics are you a reliable source?

      Not sure if you’re trolling or just a bit lost mate but you’re the only one who’s posted a source claiming turtles don’t have bones. Everyone else is aware that turtles have bones.

      E: Ah a troll after all. Started half good but honestly turned to shit pretty quick. 4/10. Turtles may have 1 brain but you, my friend, have 0.

      lmfao are you fucking joking? you made yourself look like an unreliable source by referring to such a dogshit website/article. it actually required zero help from anybody else to shoot your credibility.
