Week 4: New Observations

This week in lab, while observing in my MicroAquarium, I found a lot of the same stuff that i had before. Lots of rotifers everywhere, spirogyra, and a couple big snails. I found more diatoms, especially down by the silt at the bottom. I also finally found a Cyclops (a Copepd). There seemed to be a larger number and variety of cyanobacteria, or blue-green alga such as Cosmarium, Oedogonium, and some types of Anabaena. Most of these were colonial or fillamentous. They seem to have no preference in where they exist. Likewise they have sprung up in the past week greatly throughout the MicroAquarium. Also in the MicroAquarium I'm beginning to notice a lot more dead, and emptied protist and single celled organisms. Lots of remaining seed shrimp cytoskeletons, and lots of clear cells that were green and vibrant last week. Unsure whether this is due to lack of oxygen or they no longer were able to sustain in the given habitat afforded to them. Either way it has become more prodominent, especially in the seed shrimp it seems.
