Life under the microscope #2
Hi again.
A few more microscope videos.
The first shows some navicular (boat shaped) diatoms. These are amazing little creatures that have silica skeletons. They are responsible for the formation of diatomaceous earth (aka Fuller's Earth or kieselguhr) which is used as filtration media for swimming poors and also occasionally as a polishing agent. It consists of the diatom skeletons which are porous and quite abrasive. There are many varieties with different shapes.
The next video shows a single strand of algae. You can see the segments (individial cells). As the focus is changed you see some sgments that contain bacteria. They've entered a damaged section and are chowing down.
The last video shows more paramecium. These are much clearer than the ones in my previous post.
The level of magnification in this last video is x400. These paramecium are around 50 microns in length.
For comparison, human hair ranges from 18 to 180 microns in diameter.
There are some oval shaped bacteria amongst the paramecium but these are huge compared to some types.
The smallest bacteria are around 0.37 micron long so they would be almost invisible without greater magnification.
The sheer variety of microscopic life is amazing and I find it a genuine thrill to look at some of these critters live.
I hope you enjoyed these videos.
Bye for now.
Richard
Hi ozricho,

Wow! Thank you so much.
I used to love using a microscope when I was a child. I enjoyed the lab lessons so much and my dreams was to have a microscope at home but my parents were not able to afford it. I have almost forgotten what kind of beautiful pictures you could get so thank you for showing your videos and bringing up some great memories :)
Have a lovely day!
Thanks for the message. I'm glad you enjoyed the videos. :)
Hello! A pleasure ♡
Oh my god, these videos are from another level, I loved it, life can be as small as it is big!
Thanks. I'm glad you like them.
What a wonder to find science here on steemit. I am a marine biologist and I completed my thesis with a microplankton. I currently do not practice the biologist profession. You brought me many memories of my study times. A big hello @ozricho
Hi. I'm glad you enjoyed the videos. I love exploring the micro world. A big hello back!
