Old observations

(To @manup) I am extremely sorry for being late. The above gallery shows a trapped merismopedia in between the glass slide and microwells PVC slide. Here’s the messy time lapse videos of another merismopedia sheet:

Time lapse 01 of 105133-03-AK
Time lapse 02 of 105133-03-AK

I wanted to see cell division of the bacteria. It took an hour to make the second video. But no cell division was seen. The reason may be unfavourable condition as suspension of moss got mixed with it. The sheet was moving slowly. If you see the first time lapse carefully (at the begining) you will see a long green thing beside the merismopedia sheet.

Some other observations:

Amoeba? 108935-02-AK
A sample from an aquarium.

Colpoda? 108935-06-AK vid1


Another colpoda? 108935-07-AK

A spirogyra? 108935-09-AK

Some pictures:

These are old observations (about a month old). I am too busy to make a new observation as exams are near (to be precise, I may not make any observation at all this year). But I am collecting samples like pond water (to make some bottle ecosystem) and moss. I collected this plant (local name ‘Topapana’) and made two large water bottle units:

108935-17-AK plant. Many things (snails, nematodes, green hydra, copepods, spiders, so on) were found in their roots and in between their leaves. I will make another post on it. Please identify the organisms.

    What a wonderful series of observations @Akib. I am so proud of your dedication and just clarity of vision. Just stunning videos!

    Will go through and start identifying as many creatures as I can – just wanted to say what a beautiful work. Thanks for sharing.

    Also; you can often just make posts of data you have collected even if you are thinking about that data. Foldscope community is much like a shared lab notebook – so you know and can remember things you noticed in the data sets when you collected them.

    Keep exploring..

    @Akib. Great work. The Merismopodia movement is mind-boggling. One way to see events that might take a lot of time is to use timelapse. LapseitPro is a good app.

    My guess is K04 is a cyanobacterium.. Perhaps a break off of the MErismopodia?

    That unipodal amoeba is likely to be Naegleria

    The Chewra Dwip mixed water sample has an excellent Euglena.

    St, Martin E01– diatom

    F01; diatom and what is that in the bckground, a nematode?

    Moss suspension H01-H04 all look like Colpoda

    Can 108935-03-AK (B in B01 video) be Naegleria fowleri (the brain eating amoeba)? Who knows! In F01 video I called the blue nematode like thing as F. Actually, these names are only for youtube videos. When I make a video of an organism and upload it, I name it with a letter (example: the amoeba in B01 video is B) and add a number after it to indicate the number of video I made with it (example A04 is the fourth video of A / 108935-08-AK). When I will run out of letters, I will use two letters (like AH). If it runs out again (which is very unlikely to happen) I will use 3 letters . It will go on in this way. I am trying to culture these in my bottles. The bottles that contain Topapana plant are the most biodiverse ones.

    I used Flamelapse to make the time lapse of merismopedia.

    Thanks to both of you for the appreciation and special thanks to @Laks fo the identifications.

    Wow, such a cool post! For the first time, I have seen a Merasmopodia. Any wonder why those single cells are clumped and move the way they do?
