Day 5

Observations:
      Day five observations took place on November eleventh at one p.m. till two p.m.. When I first started looking at my Micro Aquarium, I noticed there were not as many organisms swimming around as there has been the passed few weeks. I figured that it was because most of the food they were eating has ran out by now. The first new organism I observed was a Litonotus Cygnus. This organism is large and looks like it has a long neck which is its ingestion region. It has two Macronuclei that are in the centre of each cell body and a contractile vacuole that is near its posterior region (Patterson pg.133). Next I found an organism called an Actinophrys (Patterson pg.133). It has a very interesting structure, it has a round center with long and thin spike looking structures which are called Axopodia coming out of the center all over. These act as their arms to move around and to capture its food (Patterson pg.133) I also saw a lot of the same organisms from past weeks.

Day 4

Observation:
         Day four of observations took place on November third. One of the first things I observed was an organism called an Paramecium Bursaria (Rainis Pg.107). It was a bright green color that I think came from it's vacuoles in it's body and looked like it had little hairs coming out all over it's body that you can see in a picture of it bellow. The next thing I found in my Micro Aquarium was an organism called a Tachysoma (Patterson Pg.125). This organism has dorsal brisles all over it's body that you can also see in a picture bellow. One of the last things I saw was a type of Rotifera called a Philodina Rotifera. This kind of Rotifer has two ciliated wheel organs it uses to capture it's food (Rainis Pg.188). It likes quiet water found around soils or sands I also saw alot of the same Rotiferas that I have seen in the past few weeks.
