Week 5


This week the plant growth had pretty much covered the entire area of the micro aquarium. I saw several square shaped organisms that could possibly be tabellaria. I also saw what appeared to be a bunch of pinnularia, a type of rod shaped diatom. There was also some sort of slow moving snail like creature. It appeared to have a shell and inched its way along the aquarium.

Week 4

I saw much more algae growth today.

I saw a volvox swimming slowly around eating. They are called lecane, however there are too many various species to classify it exactly.

Inside of some of the bigger plant cells or growths there were large colonies of what appeared to be young euglenoids. I couldn't tell for sure what they were because the microscope could not go to a higher power to view them in more detail.

Week 3

I saw a giant oxytricha eating and moving very slowly. It is swimming around with several smaller and faster tachyosoma.












There was a big green object that had spikes coming off of it. It appears to be a centropyxis aculeata.










There was a slow moving amoeboid protozoa of the pelomyxa species.

Week 2

Today I saw more movement than I did when we first made the aquariums. I immediately saw a group of several creatures that were oblong in shape with what appeared to be flagella on one end and cilia on the other. I believe it is an Euplotes. See picture below:











I then witnessed a larger creature that was moving very slowly. It must not like the light because it only briefly came out of the soil at the bottom of the aquarium. It appeared colorless and I don't think it had any cilia or flagella. It might be bursaria.

I observed several types of algae, including cosmarium and filamentous.

I saw at least one epistylis.

Week 1

This week we set up our micro aquariums. I used water sample #4 and added both plants 1 and 2.

4. Holston River along John Sevier Hwy under I 40 Bridge

4. Holston River along John Sevier Hwy under I 40 Bridge

Holston River along John Sevier Hwy under I 40 Bridge Partial shade exposure Holston River water Shed


Plant A . Amblystegium varium (Hedw.) Lindb. Moss.
Plant B. Utricularia vulgaris L. Flowering carnivous plant.

To begin with I did not see much swimming around in the water. I saw a few single celled organisms swimming around inside of a dead insect larva.
I saw a unique plant formation that I was told does not usually appear until later into the process of studying the aquarium.
There were several fast moving singular celled organisms eating on loose plant material.
