Wait for it !
Wait for it !
This has to be one of the coolest, weirdest and most unexpected things I've seen since I bought my microscope. I was watching what I thought was a nuclearia (branched, not stiff pseudopods with no extrusions) when the pseudopods started to pulse... then the organism just disappeared (first clip in video) . I found it again, way on the other side of the slide and then ......
Second half of video is a repeat at reduced speed. Not sure of ID beyond testate filose.
Apologies for the back and forth, there was quite a bit of action to follow for a 40x objective.

Re: Wait for it !
That was surprising! Great catch and great video. Any idea of its size?

Re: Wait for it !
Thanks 75RR-- There is a few seconds of a size metric at the beginning, but I would say the top view of the spherical shell is about 20um, the total size including pseudopods is ~60um. When walking, the length of the test is ~28um and max width is ~20um.

Sorry! Just watched again and so there is. Bad habit of mine to hover the cursor over the stop start button.

Now that is an unusual sighting! Thanks for sharing.

Re: Wait for it !
Fun! This is the ciliate Mesodinium. What you were seeing as pseudopods are the long cirri around its "waist," and a set of specialized stiff cirri called "jumping bristles." As you can see, they work pretty well. I think the cirri are a bit frayed, which is why they look like they are "branching".

Well, I never would have guessed this was a ciliate. Amazing little creature even if it does remind me of a tick

Re: Wait for it !
Some ciliates can jump so quickly that it looks like they're teleporting!
Re: Wait for it !
And always when your finger is on the shutter release. Great vid, thanks for sharing.
Re: Wait for it !
Great Find!
I have never seen this before. It looks completely different from the side.
Also very quick are these vorticella: https://vimeo.com/263421396

Makes me think the "transformers" kids play with aren't entirely science fiction . . .
Re: Wait for it !
Thanks Bob-- Wow 1200fps ! Thats serious high speed. Sometimes I try and record at 60 fps, but then cant do 4K.MicroBob wrote: ↑Tue Oct 29, 2019 6:23 pmGreat Find!

Re: Wait for it !
I cant believe how far away this creature jumped, it was seriously 2/3 the length of the slide. Makes me wonder how much "relative" vertical space there is under that slip cover. There was a fair bit of sand in that sample drop so maybe there was ample space.Bruce Taylor wrote: ↑Tue Oct 29, 2019 2:24 pmSome ciliates can jump so quickly that it looks like they're teleporting!
Re: Wait for it !
At 1200 fps this is really low resolution, far from 4k or even HD. But it makes the movement visible. Some smartphones do 120 fps at high resolution.
Re: Wait for it !
Thanks, mintakax, for a great encounter..is the illumination method a type of phase-contrast? Please speak a bit on this illumination method you used. thanls, Charlie guevara
Re: Wait for it !
Thank you Charlie-- This is straight DIC. I adjust the prism to get the best contrast between subject and background.
