Last and Final Observation

I was surprised to see the lack of moving organisms in my aquarium on this final day of research. I looked for around ten minutes and found absolutely nothing except for one organism. Of course once again it was my friend the cyclops who has been with me from the beginning. I decided to give up on my search for the larger moving organisms and moved on to look for other things. What I did find a lot of was cyanobacteria. Everywhere I looked there was cyanobacteria and other various types of bacteria. Along with the cyanobacteria were other small green celled organisms called colonial algae, which is just a type of algae. I did find a few organisms later on in my research. The first one was a rotifer which is a minute multicellular organism of the phylum Rotifera, that has a wheellike ring of cilia at the end of it. The other types were Euglenoids. These are just small green or colorless flagellate organisms.
The project has finally come to an end. I must say I enjoyed researching what really is in pond water. This makes me think of all of the types of things that are in the water when I am swimming in the lake or the ocean. I learned a lot of new and interesting things about the microsopic world and can only hope to learn more.

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.

Third Observation

At the end of my previous research time I had added a piece of food to my micro aquarium. I was pleased to see that there was much more action in my aquarium. The first thing i noticed was many spots of yellow-brown algae placed all throughout the aquarium. There were also many floating blob-like figures. I learned that these organisms were Amoebas, which are single-celled protozoans that constantly change shape. While looking at the various Amoebas I found an organism swimming around with flagella on the front and back of it. I researched and found out that it was a flagellate known as Anisonema, which is a free living freshwater Protozoan that has 2 prominent flagella with one beating normally while the other drags behind. Surrounding the area that this organism was swimming in were many pill shaped structures. They were littered all over the aquarium, so i decided to see what these things were. I found out they were diatoms which are part of a major group of eukaryotic algae. They are one of the most common types of phytoplankton and live in colonies which explained why they were placed in groups throughout my project. The next organism I found was a very interesting looking subject with what looked like horns on the front. It was a Gastrotrich which is any of the microscopic, multicellular animals of the class or phylum Gastrotricha, of fresh or salt waters, characterized by bands of cilia and by a protruding feeding apparatus at the mouth. Right next to it I saw a heliozoan; a protozoan of the order Heliozoa that has a spherical body and radiating pseudopods. I did not see any larger living organisms on this research day, but was able to see the skeletons of some of the previous seed shrimp. It was overall an interesting day of research and hope to discover more on my next day of research.
