Have a few of these. Dinos?

[Rabidbeast666]

In the last few days I've noticed a few of these thread looking things with a couple of trapped bubbles. I've been using a baster to siphon them up. Also find them floating around the edge of the glass and looks similar on top of my filter floss. Like a farm of it on my floss. Are these dinos or something else? And how do I get rid of it?

My vermited snails send out these, I'm unsure but maybe this (friendly advice )
