I had to observe an extra week because I missed a week of observation. Most of the organisms I saw early in the observations where just dead organisms now how ever I saw two alive organism. They happened to be the same species; however, they look different.  The scientific name is Cyclidium sp. (Patterson DJ.  1992.)  They are single celled organisms with cilia on one end. The have alarge vacuole that contracts regularly. It also has a big eye near the vacuole. it looked as though it used the cila to move around. It was not the fastest organism I saw; however, it was fast enough that it was difficult to get the pictures. I only saw these two swimming in the microaquarium.

This week I observed another ciliate. The cilitates scientific name is Litonotus sp. (Patterson DJ.  1992.) The ciliate was slowly moving or gliding around the microaquarium. It stayed mainly around the moss plant. I believe it to be a single celled organism. However, it looks to be complex. It is very translucent so as you can see it has large circlular insides. It has cillia on the bottom side; however, it could be all around the body. I did not see any dead ones and I only saw one of the organisms.

Observation 2

This week I observed a ciliate. This is the first time I have seen the ciliate, The scientific name of the ciliate is an euplote sp. (Patterson DJ.  1992.) This organism has a lot of cillia on one side of its body. It looks transparent to me and as if it used the cillia as limbs to move around. The euplote sp. would move throughout the microaquarium not nearly as fast as the ostracoda sp I observed last week. I only saw one euplote and none that were dead. I believe this organism to be single celled.

Observations

The first week I observed a seed shrimp. This week I noticed several organisms; however, this week I noticed the seed shrimp has grown a substantial amount. The scientific name of the seed shrimp is an ostracoda sp (Rainis KG, Russell BJ. 1996). The ostracoda is single celled. In the photo you can see the inner parts of the organism. When I first observed the organism it would only move in a circular motion is a small area of the microaquarium. Now it moves fast around the aquarium in a linear path. I observed three of the seed shrimps and one dead carcass of a once living seed shrimp.
