They don’t seem flat backed, and looks like 2 pairs per segment. Maybe juvenile? I hope these are a well know critter and someone recognized them. And I hope they are detritivores.
There really were a lot in a tiny pot, and ive made a small enclosure with the ferm they came in. Longest about 3mm, smallest sub mm. All white, translucent
Looks like they could be recently hatched centipedes. I found a small clutch of them while gardening once but they were more pinkish/blue/white
Yeah i thought something similar. Hopefully i can watch them develop in this jar and get a better look in a while.
