Week 5

Not a lot of organisms seen this week. However, a lot of bacteria was seen that I have not seen before just about everywhere in the aquarium. Other than that were a few diatoms, one very fast moving euplod. There were three more nematodes this week. I found a new creature which is the stylaria, which looks like some kind of worm.

Week 4

This week there were many different organisms but not many of them besides the rotifers. There were atleast four rotifers constantly moving and looked like they were eating all of the time. Like last week I saw a nematode. I saw one euplote, and one lacymarria. I saw the same larvae as last week, and it still was not moving so I believe it is dead. I saw the same copepod as last week that was moving very swiftly and was difficult to keep up with. I saw one new organism I found interesting which I believe was a oligochaetes because it was a segmented worm that had hair bundles. It was a very large object because I could see it without a microscope. It moved and acted like a normal earthworm eating soil. Since the second week it seems to me like there are less organisms.
