And that's why we have a lot of shredded stuff recipes.
After they realised that the subject didn't reassemble, they then went ahead to do other tests with the shredded matter, one of which was cooking and eating them.

Many, many poor little creatures with simpler or more robust or segmented nervous systems. Mostly common worms, cnidarians, starfish, metamorphosing insects, and more in that line of thought. It’s common in college bio to watch planarians unmangle themselves. Sucks for them, but they get food and relative safety, so I’ve always considered it an even trade

Based on the link sent by fossilesque@mander.xyz above, it seems somewhat unlikely. The video mentions that the sponge recombines into multiple small sponges, meaning the cells don't necessarily remember the original form.
I very well could be wrong in my interpretation though

How many animals have we ground up and put through a sieve into salt water to be this confident about it being the only animal that can do this? I need sources.

I mean, enough that manufacturing of homogenizers is a thing. https://improbable.com/...
The ad features the comforting headline: “Only the Polytron reduces an entire mouse to a soup-like homogenate in 30 seconds”

I think there's nematodes that we've blended up before, but instead you get a bunch of nematodes instead of just one.

There seem to be many of these multicellular animals who don't feel like a singular individual animal. I was commenting on a post a few months ago about the most genetically simple multicellular animal, this thing has less base pairs than most bacteria, and it can also do this trick where disassociated cells recombine into new individuals. This creature also reproduce sexually if and only if the concentration of fellow individuals is high enough, cells will just leave the body and join a new one like for fun. It really calls into question what an individual is.

I guess it makes sense that multicellularity would be more of a spectrum than a binary condition. If life evolved into it gradually, then it would make sense to find a lot of "intermediate" evolutionary states that don't feel like they're distinctly one or the other.

Don't caterpillars turn thier cells to mush when they turn into butterflys?
TachyonTele 7 points 9 months ago
My friends never seen a butterfly on grinder yet, so I think you're right.
Seriously though, the whole memory retention thing is amazing

So, my assumption is: separated cells with the same genetic code, or some other biomarker of "individuality" that might not technically be unique, will attach to each other given the chance.
Super quick research suggests they don't have organs or a nervous system, but do have specialized bits like flagella to move water through their pores/tunnels. The majority of the cells just ... are. Sounds more like a colony of genetically identical cells than a single multi-cellular creature (to me), but I assume biologists have much more information and reason to consider them the way they do.
MajorasTerribleFate 3 points 9 months ago
I dug around for a little bit, and it seems like the answer might be yes. Take what follows with a grain of salt, as I skimmed or read a few sources focused on different things and have done my best to reproduce a full picture.
First, some basic facts. Sponges anchor to the seabed (freshwater ones anchor to the dirt at the bottom of a lake/whatever). Sponge cells can move around each other and rearrange, part of their normal functioning, to keep water flowing through themselves efficiently for respiration and food capture.
Next, the mechanisms of reconstruction from a soup of sponge cells. As they bump into each other and recognize their own kind, sponge cells manage to hold together and hope for ground to attach to. They flatten out, presumably both to improve grip to the ground and to provide a large surface area for more cells to join. As long as the new colony ends up with enough of two specific kinds of cells (one makes connective mesohyl, the other makes everything else), it can grow.
The main thing I couldn't (quickly) find is specific confirmation that two healthy, stable colonies coming from a single halved source sponge can reattach, or if the reaggregation process only works following injury or during some kind of stress. Since the cells normally move around, though, it seems reasonable that this could work.
Based on all that and assuming their aren't other factors for sponge cells recognizing each other not entirely based on DNA, then presumably clones could also be attached.
Note that sponges don't actually stop growing. Their main limits are resource needs and predation, since some sea life likes to take nibbles or bites out of them (that's possibly a factor to why they are so adept at reorganization). So if your question involved cloning (rather than reattachment) only to get around a rough maximum size or early-life growth period that stops, it shouldn't be necessary.
