Couple perameciums chilling with some diatoms

Not exactly sure what this was. Possibly the same thing I caught up with later that I think may be a rotifer as well. ? This one though is slightly different. Maybe just a basic ciliate?

Interesteing shape at 3:31. Maybe something to do with what I found at the end. Maybe not.

Otherwise I caught back up with that mystery things in the last post closer up. It's very interesting looking. Almost crustacean like when looking at it from the side when it flips around.

At 3:38

Rotifer? Walking Ciliate? Some type of crustacean?

Not exactly sure what this is from and it seems like a molt from something? but I like the patterns and colors.

So, here I am at 100x and I end up viewing the business end of a pod again... lol

This time I was trying to focus more on it eating which was pretty cool

Another thing I had not seen before. Well, I've seen these before but not with flagella like things sticking out and moving. Possibly just seeing it for the first time with better optics. Now I'm curious what it is.

First few seconds is the most exciting. After that it just sat there doing nothing like I'm used to seeing.

Found this critter twice and I think it's a type of rotifer. It can move very very fast it seems. First video is the first one I found and didn't jump around like the second one I found.

1st encounter
https://youtu.be/J6_BQyQr7T4?list=PL...Dm2arNn4tDH672


2nd Maybe the same as the first one or a different one. Very hard to keep focused on and follow
https://youtu.be/aqDgkhZDk6s?list=PL...Dm2arNn4tDH672

Zoomed out and it would still just kind of twitch and bam it's in a new spot.

Then started playing around with the darkfield again and playing with the gain in the software. Made lots of things over exposed but brought out other things well.

https://youtu.be/jDDMX-Lk0qg?list=PL...Dm2arNn4tDH672

This was cool. Not exactly sure but it seemed like the cyano was trailing off new strains behind it.
https://youtu.be/wkvC2KEGZHc?list=PL...Dm2arNn4tDH672

https://youtu.be/klv8k46pOPY?list=PL...Dm2arNn4tDH672

Could really see some of the bacteria and smaller organisms moving around. Like exploring through space.

While I was playing around with the darkfield I ran accross the weird overexposed object except it had feelers, for a lack of a better word, stretching out all around it. I went back to darkfield again toward the end of this video. I didn't have it recording when I first ran into in darkfield.

It's a foraminifera I think, and I feel like it's the same as what you found later. I've never seen live one with the tentacle structure. Only skeletons that they leave in our sand.

Hypotrich ciliate or Walking ciliate like you say. He showed up mostly transparent for you, but you're right, the side view of him walking on the cyano gives him away.

Ostracod shell, such good quality!

Uronychia ciliate! Love this guy. They are huuuge (for ciliates). I've had a big bloom phase of them in a mini-tank that I threw a bunch of fish food in to see what grew. They covered the glass. They can get so large they were basically naked eye visible.
They have small cilia for normal motion, then they have the set of cilia in the back fused into a super-cilia jet-pack.

You're on a roll. Definitely foraminifera. Cytoplasm for motion and eating. Very interesting. I've seen the remains before but not one alive like that.

https://en.m.wikipedia.org/wiki/Foraminifera


I was thinking ostracod too as I have a lot of them but seemed like some of those looked a bit big but definitely looks like from them.


Uronychia.
http://www.biodiversidadvirtual.org/...ia-img172.html

Quote:
Uronychia*is another of those impossible, almost imaginary, but real beings, who live in drops of water.*A strange and not very common ciliate that inhabits the brackish waters of some coastal lagoons.*Uronychia*feeds on algae and bacteria and more than a protozoan with cilia looks like a protozoan with*▷*claws*.*

The front part of*Uronychia*carries a tuft of short cilia, they are placed in the vicinity of the mouth and thanks to them, this ciliate advances sailing, with that ballast armed in hooks of its posterior portion.*To one side and the other, the hooks of*Uronychiashow their appearance of threatening claw, appear immobile and rigid and more than useful appear to be a hindrance, yes, looking fierce.*

The thick cirrus-hooks of*Uronychia*are nothing more than cilia soldiers who have made this weapon of peace.*They are only prepared for flight, some of them, such as spring jumping*▷*when*Uronychia*is seen in danger and thus, jump and*Uronychia*flea*pirouette*disappears from the scene.*We do not doubt also that whoever dares to take a bite of this small ciliate will take a thorny memory of the experience.*

Uronychiashows in the interior the round and greenish remains of a spherical kelp, gleaned in the sediments some other while shuddering in jumps from time to time.*
The specimen of this ciliary that appears here photographed at 400 magnification with interference contrast technique comes from samples collected in the Peniscola marshes, wetlands of extraordinary interest in which among a unique fish fauna also inhabit microscopic organisms like this .

Jason- you should have a tv show like Cousteau used to have... complete with narration

"Watch the amphipod as it approaches the bacterium"



Anything new?

so here are my hypotheses on what the black algae in my tank is:

1. Combination of cyano and green hair algae in a thick mat
2. Encrusting sponge
3. Combination of dinos and cyano

Those my top guesses - it loves light and fast flow water, forms an encrusting mat and has fuzzy black hair all over... WHAT IS IT?

lol, the black mat I do not believe to be sponge at least I didn't see any kind of spicules. What I found mostly was very thick matting of cyano and some detritus and all the normal little microscopic critters that live in it. Some algae but mostly ALL cyano. A couple varieties like a little spirulina but mostly the typical cyano and something I believe to be a type of cyano I have not seen in my tank at all.

The coral sample I also saw something I haven't seen in my tank and was vibro shaped. May not be good. Did see a couple different types of dinos. Not plague like.

So it's black mat fuzzy cyano? Whoever heard of such a thing?

I've used chemiclean to push it back temporarily but it doesn't kill it completely.

How does bacteria form a solid mat? How is it hairy and doesn't blow away with high flow?

Different structure? Connectivity?

Ooh, the long-mysterious black algae!? I can't wait.
I would've bet bacterial film incorporating other random debris if we had a betting pool based on earlier descriptions.

yes. took me some time to get around to putting samples together and shipping them overnight.

now it's time for the reveal...

maybe it's an undocumented species of cyano? But usually the film is the waste product of the bacteria - so this texture and form is very alien to me.

Man getting all these uploaded has been challenging. First a unplanned reboot killed my uploads, then ran out of battery thinking laptop was plugged in killed the uploads again, then a forced windows update and reboot killed the uploads again, and then was on spotty wifi and kept stalling the uploads...

2 of the samples have been uploaded finally. Still getting the rest of what I captured uploaded...and it's the mystery black mat.


So, here's what I've gotten uploaded so far. Samples from member karimwassef.





Each sample I sliced off a chunk and sucked up some with my pipette as usually.

Have wide cover slips just for this.
