Observed a small creature in the bathroom (1 cm length) and foldscoped it, have a look at this, a little lengthy post because i felt many features are to be observed for identification

Observed its movement, the surface is slimy while it is moving.  moved forward by repeated contractions and relaxations

Its anterior end

Observed body segments and setae like structures on each segment

Body segments movement

Posterior end looks like this

I feel it as an Annelid by observing its movement,  setae , segmentation but not a hirudarian as the suckers are not seen, may be an Oligocheat. Not observed any exoskelton or jointed appendages like Arthropods
