Micro Aquarium Observation 11/14/2013

For my final aquarium observation, I went on Thursday, November 14. I observed many skeletons of organisms from before and the water had much more activity. Two of the most interesting things I observed was an annelid, more specifically an Aeolosoma, and Bryozoa. (Pennak, 1989). You can view videos of the Aeolosoma in figure 1 and the Bryozoa in figure 2.

Micro Aquarium Observation 11/11/2013

When I went to observe my micro aquarium on 11/7, there was a lot more activity than there has been in the past. I observed many rotifers and vorticella, as mentioned in the last blog. There was a lot of debris as well where organisms had left their tracks or eaten. This is the first time I observed diatoms, however. A diatom is pictured in figure 1 (Patrick and Reimer, 1966). I also saw cilia. A Stentor is pictured in figure 2. (Patterson, 1996). The most intriguing thing I saw was a Heretophery going through mitosis (Patterson, 1996). This is pictured in figure 3.

Micro Aquarium 10/31

I went to observe my aquarium around noon on 10/31. The water in my aquarium has become less clear. From a distance I saw a small white ring in the top corner, but when I zoomed in I saw many moving organisms. Most of the organisms were Aeolosoma worms (Pennak, 1989). This is pictured below in Figure 1. As I moved a little outside the circle I observed some single cell organisms called Vorticella (Patterson, 1996). This is pictured below in Figure 2. I also observed many rotifer. The rotifers I saw are called Lecane (Pennak, 1989). As far as my previous blog, the Limneas sp. were no longer living. I saw the skeletons of the tubes they were in which was interesting.
