Week #3

Last Tuesday I went to the lab and made more observations of my MicroAquarium. I learn more of the proper names for my organisms and was surprised to see that some of my seed shrimp (formerly the skeletal organisms) and died off. I thought the food pellet would have been most helpful to them, but it doesn't appear to have been.
Halteria are the organisms that I have noticed that have wavy, spindles coming off of a circular body.
Diatoms are harder to describe, but they are more of what you think off when you picture looking under a microscope. They have what seems to be a cell wall with nuclei. They are also kinda green in color.
I noticed more spyrogyra algae throughout the MicroAquarium as well.
Difflugia are the organisms that I think resemble aliens. They look like one huge alien head with little tiny legs coming off of it. They are also close to the seed shrimp and in the plant leaves and pond scum.
Of course there are still ostracods and nematoads swimming about. The water also appeared to be less transparent and full of more pond scum.
