It is not just a piece of debris. It probably is springtail remains or something. It was c shaped that’s why I wanted a side view picture but I knocked it away after watering the vial a bit. It was also kind of opalescent.
that's not something that was ever alive. A dead spring tail would look shriveled up, not to mention have noticeable limbs and such and not just a blob. I'm almost certain its just a piece of rock or some other inanimate object.
