Immortal Serpents

I came up with these guys a few days ago. It's a fairly basic symmetrical serpent swimmer that rotates around a central axis of lipocytes. They don't reproduce, but are basically "immortal":

They have a nice graceful movement; on a small plate, they kind of "walk" around the edge as they tumble, and rear up like a snake standing on its tail. They can easily get long enough to span the full 1mm diameter, with 150 or more cells. Sometimes they'll briefly get stuck on the outside edge, but almost always recover by shedding dead cells and flipping over a few times. I tried all sorts of attempted improvements - making them smarter with stereocytes, allowing them to reproduce by splitting into multiple independent pieces or budding a new egg from the center, or giving them more phagocytes to catch more nutrients - but none of them work as well or look as cool as the simpler one I started with. The heavy lipocytes in the center seem to help them have a strong center of gravity to rotate around, so they grow more or less symmetrically.

On a large, high-salinity substrate with multiple organisms, they do surprisingly well despite getting entangled with each other:

Swimmer chains a very cool and under-utilized by users. Mine are a bit different, sort of spiraling back in on themselves, and also forming folds. Then they spin around like yours, and start to spiral and fold when conditions are good. You can actually make them incredibly efficient because they're sharing so much energy.

One can get 420 on Macrophages IV and 800 on Harsh II: they get virtually all nutrients on the way out to the wall:

I have another version that pushes forward with lead swimmers, following the light in Sunlight, rearing up in the middle and falling into layers of swimmer chains. Pretty cool to watch!

There are also some other fun uses for these sorts of organisms. :)
