Pretty Cutie Manly: Jade T., Karissa C., Karissa G., Thinh P. 

1/ Organisms : Volvox sp. and Daphnia 

Domain: Eukaryota
Kingdom: Plantae
Phylum: Chlorophyta
Genus: Volvox
Defining characteristics:
What helped us identify the Volvox was it’s round shape and it’s green color.

3/ Organism 4: Cosmocladium



Domain: Eukaryote
Kingdom: Protista
Phylum: Desmidiaceae
Genus: Cosmocladium
Defining characteristics:
We had a hard time identifying this organism. After much head scratching we deduced that this organism might be the Cosmocladium, due to its round shape and green color.

General observations:
Our fourth organism, the Cosmocladium kept swimming around in circles. The first organism (Volvox), second organism (Daphnia) and the third organism (Anabaena) was stationary. It is hard to see the Daphnia because it is hidden amidst the jumble of different organisms.

  1. Hey guys, great post! I think your third organism is particularly interesting, since I believe our group saw a glimpse of that organism swimming around in the slide, yet we could not track it since it was too fast. We did not see any of your other organisms, however, which just shows how diverse the organisms are in that pond water, even though we used the same sample of water! Great blog post!

  3. Hey guys, I am so glad someone figured out what that black dot was. My group had that on our slide as well, but we couldn't figure out what it was. Also, good job on actually getting a good photo of it! However, I am curious as to how you were able to identify a daphnia in your first picture? I cannot make out in distinguishing features in the photo itself, but maybe you guys have a zoomed in version of the photo to see something I am not.

  4. Great post! Nice job identifying the Daphnia and Volvox from the mess of organism. Like Jessica I can't really see the daphnia from the first picture. I think I can make out the eye, but the rest is just lost. My lab mates and I found a Daphnia and Volvox too.
