Almost the Last Post

I have been having some serious spelling issues lately... Hopefully, this post will be free of any possible errors. I've sourced many of these images, and some of my previous ones. The water in the tank had dropped severely when I checked it this time. There were also many strings of cells, as well as several colonies of cells that were difficult to identify as living or dead.



1. This is a Coleps sp. It's very fast, almost too fast for the camera to capture. This is about the best picture I could get of it.  It seemed to be dark green in color, and it has a bluish rim around the inner cell that seems to be a membrane from the glimpses I could catch of this speedy organism.  



2. I found Dero Digitata in my MicroAquarium this week. This worm was identified by the spike configuration on its back end, pictured above. The Dero seems to like hiding in the bottom layer of the MicroAquarium, poking its head out from the dirt to grab plant matter to consume. 


3. I found this Anisonema sp. around the middle of the MicroAquarium. At least, the current middle when I took the pic.  It's not a great one, because neither of the flagella are visible... But it's the best the camera could catch. Interesting tidbit, even on the microscope, there didn't seem to be a mouth present on this Anisonema sp. 


4. I thought this picture was interesting to include. It's of an absolutely gigantic amoeba, one that there wasn't any positive identification for. This thing could barely fit inside the camera's view, thus the cutoff picture. The amoeba seemed to function through those little streams visible in the picture, nutrients being carried through them. 


5. This organism turned out to be an immature Nauplius Cyclops. I thought it was really interesting how it looked like a tiny bug instead of something you'd find in a MicroAquarium climate. Or, well, a spider... Which is a little scary. It moved in an extremely twitchy manner, jerking quickly through the water. 



There are also some organisms I spotted, but didn't grab pictures of this time around.
Here's a list:

At least one Nematoda
At least one Paranema
Many Vorticella sp. (they've showed up before!)
Lots of Halteria
One Halteria that looked ready to divide, as the movements were slowed down considerably and it was bigger than it normally was
At least one Heterophrys
2 Difflugia (showed up at least once before, last week)
Analyd that was either poking its head out of its tube, or building the tube it remains in for the rest of its life
Several Loxophyllum (they've showed up before)

There were a lot of worm droppings, just like last week.

My water, as usual, was originally found at:

 Water pool below spring. Fountain City Park west of Broadway at Hotel Ave. Knox Co. Knoxville TN. Full shade exposure Spring Feed Pond N36 02.253 W83 55.986 990 ft 10/12/2014
