On
October 26, 2012 Dr. McFarland inserted one Beta Food Pellet into my
MicroAquarium. My observation (s) took place on October 31, 2012 at
approximately 2:15 p.m. My observation (s) took place in the usual room 202 of
the Hesler Biology Building on The University of Tennessee, Knoxville’s campus
with the help of Dr. McFarland. Just like in my last observation, I used a CH30
Olympus microscope, a Sony Camera (HDR-HC9), and a Dell Computer. I also used
the corresponding remote to snap images of
interesting organisms that I found throughout my observation To observe
I removed the stand and lid from the MicroAquarium tank. Then I carefully laid
the tank on the microscope stage with the open end away from me. Since October 23, 2012 (my last observation)
and with the Beta Food Pellet added on October 26th, there were a
lot more organisms that were visible than there were in the previous
observations. To help identify organisms Dr. McFarland and I used the book, An
Illustrated Guide to the Protozoa.
The first organism that I observed
is related to the Amoebas. I observed
this using a Nikon Japan lense (40). Dr. McFarland helped me identify that it
was of the Genus Microcorycia (Bovee, Lee, Lynn, and Small 1985). This organism possesses
a finger like structure that pops out. However, during my observation (s) the
organism did not pop the structure out. It was very still. This was the only one of the organism that I seen while observing. Below is an image of the organism edited with
Adobe Photoshop Elements 7.0.
The second organism that I observed was
a Stentor sp. (Bovee, Lee, Lynn, and Small 1985). To me, it
looks like a trumpet. Individual cilia were pushing water into its funnel
during my observation(s) of it. I observed and captured a picture of it using
the Nikon lense. Below is an image of the Stentor
organism edited using Photoshop. I combined two shots of the organism the top picture shows it upclose under the Nikon lense and the bottom image attached shows the Stentor sp. under the EF 10 (1.25) lense.
The third organism that I observed
was a Halteria sp. (Bovee, Lee, Lynn, and Small 1985). There were a
lot of them. The organism moved so quickly. On the outer surface of the Halteria there were cilia flowing. I saw
the specific organism that I captured a photo of towards the bottom near the
mud.
The fourth organism that I observed
was a Litonotus sp. (Bovee, Lee, Lynn, and Small 1985). Notice in the
image below the vacuole on the back end. According to Dr. McFarland, it is a contractual
vacuole that gets rid of excess water in the cell. This organism moved very quickly and I seen about 3 or 4 throughout my observation (s).
The fifth organism that I observed
was very still. It is an Arcella sp. (Bovee, Lee, Lynn, and Small 1985). It just layed
and kept very stiff in the middle of nowhere.
The final organism that I observed
was an Amoeba Radiosa sp. (Bovee, Lee, Lynn, and Small 1985). This organism catches
its observer’s eye as you can see in the image below. While I was observing this organism it moved at medium speed in the middle of the aquarium. Dr. McFarland said during
my observation(s), “It can become one of your worst nightmares at night if you
think about it too long.”
Overall,
this was my favorite observation out of all because I found a lot of organisms.
I’m sure there were more, but the Genus Microcorycia,
Stentor sp., Halteria sp., Litonotus sp., Arcella sp., and the Amoeba Radiosa
sp were the ones that Dr. McFarland and I received the chance to capture. Like
instructed on my last observation(s), at the end of my observation(s) to
replace the water that may have been lost somehow, I added more to it with the
clear water bottle that he provided.
