Here's another of my attempts at Video Microscopy with the SP100 microscope. These Euglena show up really well against the black background and you can see all the shifting colours inside them as they gently spin around and glide through the water.

  • How big are these critters?

  •  Hi. They are 25 - 100 µm

  • Cheers! My microscope is in pieces at the moment but I hope to be doing more in the summer.

  • ;-) Much appreciated.

  • Thanks. I just picked one of the free youtube tracks (using Audio swop feature) and I can't remember which one. If I stumble across it again I'll let you know.

  • Thanks. The 400X is from 1 min 21 seconds into the clip until the end. Glad the vid is useful!

  • @Darko2625 I don't think there are genders for protists. It may be okay to refer to them as "her" and "him", although they are not really any gender.

  • and your correct borumune, the red "eye spot" is used for light sensory, as these creatures live in the water, the "eye spot" will direct them to the surface :)

  • Brilliant, the Euglena is on of the most beautiful protazoans.

  • thanx man! great video! helped me a lot!

  • Name of the song please?? Great Song and great video!

  • @ZakX11 they are too simple to be plants or animals. Plants and animals have specialized cells. The are eukaryotic, unlike bacteria or archea so they belong to their own group/kingdom, protista.

  • Great Video! How much did your microscope cost?

  • 0:58

  • @borumune Something like eye,but it's not exactly the "eye". That's like ambient light sensor for her. :)

  • @ZakX11 Because animals and plants are both multicellular. This is a single cell.
