Where did you locate that? What medium were you using to proliferate it?
@davidonfim2381Күн бұрын
As the description says, I found it in a sample from a freshwater lake. I used a jar to pour water on the sediment around the shore (to suspend some sediment in the water), and then I took a sample of the water. I also put a couple of dead leaves and sticks from the bottom in the jar. Since then it's just been sitting in my windowsill. I believe I specifically took this sample from the sun-facing side of the jar, right at the boundary between the sediment and the water column. This particular lake is a low-nutrient, relatively acidic lake in the New Jersey pine barrens.

I will never get over how small these organisms truly are. I mean here's a perfect example. The cover slip in on thin film of water on the slide - AND STILL this tardigrade is walking upside down on the slip! I HAD to share this on my Facebook and Instagram accounts with a link back to the video of course!

When I was quite young my parents bought me a microscope (cannot remember if it was Christmas or birthday). Remembering it, it was quite a basic one, it could magnify up to 250x and it used a mirror to direct daylight from below up through the specimen. The problem was that's all my parents did... they didn't really think about showing me how cool a microscope could be. Sure it came with half a dozen prepared slides (feather, fly's wing, petal, and so on), which I looked at... and that was it. I wasn't particularly imaginative, so I don't remember getting soil from the garden, or trying water (although 250x was probably not high enough) and so on. Now I know what I was like as a child, I think if my parents had shown me how fun the microscope could be I would have been fascinated with all the things I could look at. That was around 40-42 years ago. Now I sit here looking at all your videos, and waiting until I can afford a microscope of my own!

I think what I love with this one is - aside from the amoeba - there are even tinier microbes darting about... it gives weight to the idea that the life in a drop of ditch water is almost infinite. Does the drop of water to them feel as large as the earth to a human being?
@davidonfim238112 күн бұрын
There are microbes even smaller than those too. Bacteria are all over the place, but many wouldn't be visible in this video because they're too small. Viruses are even smaller. They are nowhere near that small in relationship to a drop of water though. My cover slip is 20mm x 20mm, or 20000um^2. If we take a hypothetical microbe that is 25um^2 (this amoeba was larger), that makes the cover slip area only 800 times larger. That difference is not even the same as the difference between a human and a small town, it's more like a human in an area the size of a school, or a few city blocks.

What are the different coloured circles within the amoeba?
@davidonfim238112 күн бұрын
Good question, I'm not sure. I couldn't tell you what anything in this particular amoeba is. More generally though, you can often see prey at different stages of digestion inside of amoebas. Amoebas also sometimes take in bits of their surrounding (tiny grains of sand and dirt) into their cells, for unknown reasons. They also sometimes have lipid globules, crystals, glycogen bodies, and endosymbionts. You can read more about those on arcella.nl/inclusions

Watching it shows how much of a "vortex" it creates in the water when even quite large organisms are drawn towards it. And how do you measure them?
@davidonfim238113 күн бұрын
Yep! I've yet to see anything actually get caught though. My microscope has a touch screen that allows me to just click "measure", set the objective I'm using, and make a line. It then just tells me how long that line is. It's super convenient, although sometimes the touch screen isn't sensitive enough or will detect the touch very slightly to the side where I intended.

Is there any possible way of showing the droplet before or after viewing what's in it?

@@Ashleygeneralstuff Yeah, it's absolutely amazing how many amazing things there are all around us (and in us, and on us) all the time. Many of them aren't particularly rare or hard to find, but 99.9% of people blissfully go their entire lives without having a clue simply because they're too small to see. I wouldn't mind sending you pics of the droplets, but there are plenty of other channels and websites that will show you this. I don't think youtube will let me link you directly, but if you haven't already, you should check out @Microbehunter. He makes very detailed videos and livestreams where you can learn how he prepares slides, how he cultures certain microbes, the biology of the microbes, etc.

It is always surprising that the prey doesn't realise what is happening often until it is too late and there is no escape. I assume as they don't have brains they have no consideration for self preservation. Perhaps they cannot feel they are being engulfed.

Glad you like them! I do recommend getting a microscope if you can. They ARE somewhat pricey (the one I have is currently $300 in amazon, although it was a fair amount cheaper when I bought it), but they do entertain you for hours. It's great because you can find things to look at throughout the year, and you never know what you'll find. If you buy the right microscope, you don't even have to worry about eye/neck strain or about buying things like a camera because they have a camera and screen built in, so it's really convenient.

@davidonfim2381 Thank you! I've seen one second hand that says 200x to 5000x but I am wondering if that is 200 is too HIGH as a minimum.
@davidonfim238122 күн бұрын
@@Ashleygeneralstuff 200-5000x?!!!! 200x IS a bit high as a minimum. The lowest magnification on most light microscopes is 40x (4x objective and 10x eyepiece). You often want to use the low magnification to find your subject. A 5000x magnification is a wrong though. The physical limit for light microscopy is about 1000-1500x, so I wouldn't trust anything saying it can magnify more than that. Most of the time you don't even want that much magnification, as the depth of field (how much of the image is in focus) gets smaller the more magnification you have. If you want to look at amoebae, rotifers, ciliates, and tardigrades, you generally want a total magnification of about 400-600x.... or even less. Seeing the fine details in things like diatoms does require more magnification though, but that will obviously mean a more expensive microscope as well.

It was pretty easy. After taking a hot shower to open up the pores, I squeezed the side of my nose to push some sebum out of the pores. Then I used a scalpel blade to (gently) scrape off the sebum, and I placed it in a slide with mineral oil. After spreading it around, I just added a cover slip on top and started looking under the microscope. It took a little while of looking, but I found both species of human demodex (brevis and folliculorum). Interestingly, they also last quite a while in the oil/slide (I think at least a day, if I remember correctly) if they made it onto the slide unharmed.
