Semaine Deux


We are now in the second week of observation of the microaquarium. When i first walked in and sat down today i first found a new organism that looked like a octopus with only 3 tentacles. The "tentacles" continuously receded and elongated into the body of the microorganism, seeming as if it may be crawling on them. It did not move very fast at all. I had found a better example out in the open but when i took it to the other microscope to take a picture, it had moved. I did however find another one, but this one was on the side of the microaquarium and didn't pose for a very good picture. The picture of the unknown organism is at the bottom of the page and i will try to do some more research on it next week. Another organism i found for a second, but moved extremely fast and i lost it was a wormed shaped very small organism that wriggled and spasmed around very fast, it looked almost exactly like a stringy earthworm under the telescope. Both the "tenticled" organism and the earthworm shaped organism were viewed under high (400x) power and are extremely hard to find when just looking for them so i don't know if i can ever get a picture of them. Other than these two unidentified organisms i found out that the spider looking organism that was jumping around in the microaquarium was actually just a juvenile cyclops of which the adult version is pictured on the top. I also found out that all of the plastic bag looking things on the bottom of the microaquarium that floated above the debris in the very bottom were actually a whole bunch of seed shrimp carcases that the seed shrimp apparently sheds during the course of its life. This also means, because there were so many that the microquarium contains a large population of seed shrimp. One of the many seed shrimp in the microquarium is pictured in the upper middle on the right of the page. Hopefully i can get a better picture of one of these soon. They are kinda hard to get a picture of out of the debris at the bottom. The organism in pictured in the lower middle of the page that i have seen a couple of times in the microaquarium and believed i have described it as a jellyfish looking thing was actually identified as a Rhodeford but Dr. McFarland. My microaquarium is full of these little critters. Well that is it for this week, see you again next week!
