Rotifer Feeding.

[feebix]

I was looking at one of these little guys last night and I haven't managed half as good a video as this. Fantastic! As far as I know my diaphragm doesn't actually move. That's something I'd better go and check on I think because this videa is now my benchmark ! If I can manage this sort of quality I'll be very happy!

nice video.......i firstly saw watercurrent....nice thnx

[Spyro543]

This is gonna give me nightmares...

jk :D Good video, neat to see rotifers. I'm gonna find some paramecium in the creek beside out house :D

If you watch the video I posted a short while ago on Oblique Light you can follow the process from centred condenser aperture, to a position where the light cone passes outside the field of view. You will see a setting more or less the same as the one I used for the Rotifer video towards the end of the clip. It's really just trial and error, choose an offset that gives you the kind of image you want.

OMG SPAZ BUBBLE seriously tho i like rotifers

[GmodMaster14]

saw one in science class, microscopic vacuums basically

[dlindeman]

Did you use a fluid thickener to get it to slow down ?

[EDFWilliams]

@dlindeman No. This is a direct lake-water preparation about 400 - 500 micrometers thick. The Rotifers die quite soon after a preparation is made so the observations have to be done without too much hanging about.

[dlindeman]

@EDFWilliams Thanks for the reply .What do you mean by preparation? Rotifers can be rehydrated on a dry slide .They do that suspended animation thing.

excellent

[fsmelo87]

awesome, as a biology student I was facinated the first time I saw a rotifer on a microscope

[VernasHalo]

hehe nerds

[132BigBoy]

inteligent people that is not such a basic primate like yourself that only thinks of food and screaming drunk

[artman40]

These animals deserve more recognition.

[darianf68]

wat are those little cells that the rotifer was eating?

[EDFWilliams]

Many of the particles are bacteria.

[NGShade]

does that have eyes? looks like it came from Spore

[TheSonOfDumb]

It doesn't have eyes although it can sense prey somehow.

Anyways, is it just me or is there no water in there? The ciliate (I think) just left of the rotifer at 0:01 seems to be having trouble moving. Is it just me or is the contrast and other stuff were changed in this vid?

[dideoxynucleotide]

They have eye spots. There photosensitive. It's not really vision, but it's an early antecedent.

[chaosman96]

its the ultimate micro killing machine!

[EDFWilliams]

Yes. I set up for Köhler -- then offset the condenser diaphragm (NA 1.4 Aplanatic).

[BirdWhisperer46]

@EDFWilliams Could you explain the process a little more? Are you first centering the condenser, then decentering it? By about how much?

[fpelectronica]

Great video. Do you use oblicue ilumination? Thanks.

[granyoga]

Is as the Spore, lol!

[antipisto]

Thank you for posting these wonderful videos :-)
