This fella is for sure slower than I usually see for nematodes. I looked it up and it looks like microworms are a type of nematode. I have some other footage of nematodes and they are usually thrashing about quite violently. And 100% these guys are bigger than what I usually look at. I like the sense of scale this video brings since a lot of bacteria and some protozoans are in the shot with this big fella.
