This thing is the scumbag of the micro world lol and what would happen if you ate that thing?

[EDFWilliams]

@COXY41567 If you have ever quenched your thirst from a stream you have ingested very many small protists, algae and fungi -- not to mention bacteria.

[EDFWilliams]

The genus is not very big. But I don't know them very well. This one might possibly be V campanula but that's a guess.

[EDFWilliams]

Keep looking. There are at least four food vacuoles visible... they all contain bacteria.

[EDFWilliams]

Most of these videos were taken using phase contrast. But in some case polarized light and a red retardation plate were added to make birefringent inclusions more visible.

how fast do micropes evolve?

[EDFWilliams]

Microbes: bacteria, such as E coli for example, divide once every 10 minutes in culture. One is a million on the average is a mutation.

HOw do some people think this stuff is boring??? its awesome!

[Healer7]

these little buggers ate up my algae specimens as I was microscoping them in a field lab

thumbs up if you thought it was a spore creauture on the thumbnail

With your eyepice you'll achive at least 1000x wich is about the maximum for *every* optical microscope on the world. You'll see some big bacteria in there. But as I said, working with the 100x is a bit of a nuisance. Try using the 40x or 10x, they are enough to see algae, ciliates, flagellates and whatever single celled stuff in great beauty.

Water fleas are probably even too big four your smallest magnification let alone the fact that they don't really fit under a cover glass.

@weardrake

I think ozzymandy was lead to a wrong conclusion by your declaration of magnification. 100/1,25 ist the magnification of the objective lans and its numerical aperture. This multiplied with the magnificaion number on the eyebiece (usually 10x - 20x) is the overall magnification of your microscope. The reason why you didn'T see much is proibably because it was too high. 100x objective lenses are requiredwith use of imersion oil and accurate cover glases. Else everything becomes blurry

All this video is missing is David Attenborough's voice.
