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.
