Observations - October 24th, 2008

The overall growth in the aquarium seems more active. I think I spotted the same midge from the previous observation. He was located in the same place (the edge of the sediment). It appears much larger and everything is more defined. The insides were visible and I could even see the digestive system working. The legs were also visible and it moved in a very docile s movement. The tail also has small hooks that act like anchors, holding it to the dirt. It appears that it prefers the soil rather than the open aquarium. Cyanobacteria is located throughout the aquarium in larger amounts and is much larger than any other bacteria. They are linked together and appear to be a bluish green color. I also found Euglenoids in large amounts as well. The have green flagella and a brown interior with a red spot for an eye. The move very slowly and seam to float around with the ability to crawl. Pond scum is also abundant in the aquarium. The are distinct chains of cells with crossed, green pattered inside. The Bag Traps also seem to be more defined with long extending sensor hairs.

Initial Observations:
- Ultricularia vulgaris (Plant B): I observed many "bag like" contraptions attached to this plant. Apparently it is designed to capture the microscopic animals floating around. In one quick movement the bags suck in the animal and surrounding water. Hairs on the outside of this bag act like a trigger for the reaction.
- I also observed many other micro organisms floating around. Of which is a single cell organism that was stationary with hairs on either end which move with quick speratic flicks. These hairs appeared green. Possible cyliates - oxytricha?
- A creamed colored, multi-cellular s-worm. Moved with very speratic movements, almost random, located in the middle of the aquarium's water.
- Located at the edge of the aquarium's sediment sample I found a worm-looking organism. The exoskeleton was visible and almost clear. It only exposed half its body length at a time. The head appeared to have "eyes" and very short "antennas" in respect to its body length. Hairs located on the tail and moved consistently in a S shape. This organism is very possibly a mosquito larva or more likely a midge.
