Fourth Observation

At my first glance of my microaquarium I was very pleased to see how busy it had become. Not necessarily with large organisms moving everywhere, but with smaller life forms. The most occurring life forms in the micro aquarium was cyanobacteria and other types of bacteria. They were covering the entirety of the aquarium anywhere you looked. Green Algae was also a highly occuring life form. It too was speckled throughout the entirety of the aquarium. I also spotted a lot of euglenoids, which are a type of flagellate commonly found in freshwater. While observing one of these euglenoids I caught movement out of the corner of my eye. I moved around with my microscope until i saw an old friend. It was the Cyclops I had been observing during one of my first observations. I was surprised to see that he was still very much alive. I also ran across another previous old friend in my aquarium. It is an Ostracod also known as a Seed Shrimp. He was doing what he was usually up to when I see him. Eating throughout the plant area in my Utricularian Plant(Plant B). While observing this I noticed little sacs coming off of the stems of the plant. I was explained to that these sacs use their flagellate like tendrils to feel when prey is close, so that they can open their valve to suck whatever may be in these tendrils. Once an organism is in there it cannot get back out, which means it will die and be digested by the plant and various other organisms that feed on the sac. Another organism I saw was a rotifer which is an aquatic multicellular organism that has a ciliated wheel-like organ for feeding and movement. The last organism I was able to notice was a nematode. A nematode is an unsegmented worm with an elongated rounded body pointed at both ends. They are mostly not harmful but some are parasitic.
