MicroAquarium: Week Five

As usual, there seems to be little activity in the other two plants while the Uticularia gibba houses much activity. The mesh-like root system from the gibba I observed growing up the right side of the tank in week three of observations is growing thicker and spreading. I was surprised to see a great amount of activity in this system, observing the two species of Aeolosoma tangled all around the structure.

While searching the tank for other organisms, I large tadpole-like organism swam swiftly across my view. It was hard to find again due to its sporadic and quick nature and I was actually able to follow the organism by the naked eye, looking out of the sights of the microscope and using my naked eye to track the creature. I later found that this creature was a Copepod belonging to the genus Cyclops.

There was also another interesting organism that I observed in the root-like system that meshed along the right side of the tank and also observed towards the bottom of the tank in groupings. This organism was flat and clear and did not make very sporadic movements. I later found that this organism belonged to the genus Euplotes with a specific species unable to be named.

As you can see in the above image taken at a side view of the organism, the organism is flat and moves along by small appendages underneath itself.

The MicroAquarium: Week Four

As usual, the Utricularia gibba seems to be growing ever denser and spreading. The worm-like creatures viewed upon the last obersvation I was able to identify as the genus Aeolosoma but the species was unable to be identified do to the lack of vision of the initial organism. Also, this image that I captured is demonstrating this organism's asexual reproduction by pinching off towards the middle of the organism to form another.

In further inspection towards the bottom of the tank, I noticed the dead exoskeleton of the dead seed shrimp I had observed two weeks prior. Around the skeleton, I also noticed another worm-like creature that looked very similar to the creature observed around the gibba. Dissimilarly, this organism had more of a rounded head. I found that this organism also belonged to the genus Aeolosoma but the species was also unable to be identified for lack of visible detail.

2. Aeolosoma species b. (Pennak, pg. 324).

Many single celled organisms were also observed throughout the many weeks of observations, but I was able to identify one larger one that moved sporadically, pulled along by a flagella that moved in a spiraling motion. This organism belonging to the genus Anisonema also had another flagella which did not seem to move and was idly dragged along.

The MicroAquarium: Week Three

Even more so, I have noticed an overall growth in the Utricularia gibba as the week has progressed. There seems to be a kind of webbing of a root system from the gibba traveling up the right side of the aquarium. There is also a growth of activity inside and around the gibba. There some particularly interesting worm-like creatures that I have not been able to certify the species or genus yet. I also noticed a growth of single celled organisms ranging in many different sizes and shapes. Some even have visible flagella which spur them along in very sporadic movements and paths. Also, I have not seen the seed shrimp that I observed last observation. I hypothesize that he has either died or is hidden beneath the sediment where I found it crawling along.
