List of organisms

1. Euchlanis sp. rotifer

2. Litonotus sp. 

3. Coleps sp.

4. Halteria sp.

5. Arcella sp.

6. Cyclops sp.

This week I noticed two large Cyclops sp. They were both visible without the microscope and were extremely large under it. Below is a picture of one.

There were also large amounts of green all over the MicroAquarium. I took a picture to show how much green was around the entire aquarium. Below is the picture.

I was also able to see the Euchlanis sp. rotifers (Pennak, 1932). The Coleps sp. were also still visible swimming around (Patterson, 1992). This concludes the observations of this MicroAquarium.

This week the life was still moving rapidly around. I spotted many of the same organisms, specifically the Euchlanis sp. rotifers (Pennak, 1932). and the Litonotus sp. (Patterson, 1992). There were many green pigments, many of which looked like small weeds. The amount of green growth was increased significantly. Another new discovery was an organism that could be spotted moving without a microscope, a Cyclops sp. There were no pictures taken this week, but I will post more next week.

5. Arcella sp.

This week a food pellet was added to the MicroAquarium. This increased the amount of living organisms greatly. I was able to see many Euchlanis sp. rotifers swimming around and them eating a dead organism. The Litonotus sp. was also seen again, looking the same as last week. Overall, the MicroAquarium had much more life and I was able to identify some new organisms.

The image below is a Halteria sp. (Patterson, 1992).

The image below was identified as a Arcella sp. (Patterson, 1992).

Below is the Euclanis sp. swimming (Pennak, 1932).
