Chaos carolinensis, a very large amoeba
Chaos carolinensis, a very large amoeba
Chaos carolinensis is a very large amoeba, so large in fact that I could not get the entire amoeba in one picture. So, I decided to make a short video to show how large it is. You can see the protoplasmic streaming and the many nuclei characteristic of this amoeba.

Could you tell a bit more about where you got it from, how you retrieved the specimen and how you prepared the slide/sample.tlansing wrote: ↑Tue Aug 31, 2021 7:52 pmChaos carolinensis is a very large amoeba, so large in fact that I could not get the entire amoeba in one picture.

Re: Chaos carolinensis, a very large amoeba
@75RR: Thanks!
@Wes: This was completely serendipitous. I had made a collection from a small pond (really a holding pond) which was next to a much larger lake in NC. This small pond does not go through cycles of drying out/refilling after rain, so the environment was pretty stable. I had allowed the jar containing the sample to sit for a while (weeks), sampling it occasionally to see what emerged. I actually saw Chaos twice in this same collection. I had simply removed mud, etc from the bottom of the jar, placed it on a slide, added a coverslip and took a look. I took a darkfield photo using a 6.3X objective (below), but I think the video gives a better idea of the size of this amoeba. Glad you liked it!

Beast of an amoeba, nice video, well done.
Re: Chaos carolinensis, a very large amoeba
Thank you for the details. This thread has inspired me to collect some mud and check whats living in it.tlansing wrote: ↑Wed Sep 01, 2021 10:19 am@75RR: Thanks!

@Chris Dee: Thanks!
@Wes: Thanks, Wes. I have made it a habit to always collect some of the mud at the bottom of the pond or lake. I use a turkey baster to collect mud and water. I always also let it just sit and develop over a number of weeks to see what emerges. There are always a number of interesting critters in there! if you have ever looked at the fantastic book by Kreutz and Foissner containing superb photos from some ponds in Germany, they show a number of bizarre and beautiful ciliates and other protists that they found in the mud and sediments.
