Nematode or not?

Is this video of a nematode or something else? It does not move like a nematode that I have seen before, but it looks like it may have a stylet forming.

I soaked a strawberry leave in water and a petri dish for 3 weeks and I am seeing these worms in the water now. The same strawberry leaves, three weeks early, had nematodes on it identified as Aphelenchoides sp.

Location is Southern Central British Columbia, Canada.

I don't think any nematode. I have seen something similar and I think it was a bdelloid rotifer.

Thank you, Peter Freimann and apochronaut!!!

"Bdelloids can only be identified by eye while they are alive because many of the characteristics significant to classification are related to feeding and crawling; however, genetic identification of bdelloids is possible on dead individuals. Once preserved, the individuals contract into "blobs" which restricts analysis.[16] There are currently three morphological identification methodologies, two of which are considered dated: Bartoš (1951)[17] and Donner (1965).[13] The third method is a diagnostic key developed in 1995 by Shiel.[16]"
