How Many Critters Can You Identify?

[paparoof]

Cleaning some "oook" out of my tiny refugium tonight (IM 30L AIO tank) and thought I'd put a drop or three on a slide and check it under the microscope.

Looks like I've still got dinos but I haven't ID'd what kind they are yet. I haven't noticed them in the display in quite some time, but interesting to note they're still present.

I'm mostly interested in what the slug-looking fellow is (best viewed in the medium magnification video) and also the long, thin, two-segment guy at the top of the high-magnification video.

Let's hear your thoughts.






Bonus points if you can tell me what old TV show I have on the background.

Nice videos of who knows what microbial life you’ve got growing there? All I can think is that they do appear to be likely voters in the next election. I’m pretty certain other people will have a more specific ID for you but I thought I would get the conversation started.

Looks like ostracods; though there are roughly 70,000 species of them, so this hardly narrows it down. The vast majority, if not all, are beneficial, and play a key role in the marine ecosystem

Couldn't really id any of this but I can see some maybe by type. I see a diatom, an amoeba, a predatory ciliate, maybe some multicell algae, maybe heterotrophic bacteria, and loads of scattered bacteria poo haha. If one could get some really clear pictures of how they eat, and what their insides look like that can help narrow down. Not a bacteria expert just know some things.

So are the little round zoomy guys ostracods and not dinos?

Do you have reason to believe they are dinos? I would assume they are ostracods if they were taken from the water column, though if there are no front appendages, it could be dinos.. :/

I was assuming they were dinos because I've had dinos in this tank before. Ostreopsis though, and these don't behave the same way.
