An additional Closterium picture

Dr. Mcfarland was able to take this picture for me. it is a real good shot. The terminal vacuoles at the cell tips hold vibrating crystals of barium or calcium sulfate, the function of which are unknown. Brownian motion causes these microscopic particles to move erratically due to the impacts of collisions with the surrounding liquid molecules in which they are suspended. This explanation is from a page of Connecticut College's website. It is describing the red ball of crystals at the end of this desmid.

Changes from Beginning to End

There have been many changes from when I first started the microaquarium until now. New organisms have seemed to appear, while others died off. While examining the bottom of the tank I found numerous dead organisms. A big change I noticed was the amount of cyclops found in the tank. When I started, there were only two or three, but at the end, there were atleast fifteen in the tank. Some of which were females with egg sacks. Another change I noticed were the amount of protists suspended in the water. In the first couple of weeks, this was not really visible. After the feeding, the amount of protists in the aquarium multiplied tremendously. The picture shows the great amount of protists suspended in the water. The other organism is a rotifer.

gastrotricha

Gastrotricha is a multi celled moving organism. It is not photosynthetic. There are a few in the microaquarium. This was found near the bottom of the tank in the corner.

The above is Vorticella. This organism is very abundant in my micro aquarium. They can be found anywhere; top, middle, or bottom. They are a moving protozoa with a very long flagella. It is also a single celled organism. It does not have chloroplasts and is not photosynthetic.

Fragilaria

The above are Fragiliaria. They are surface water algae. It appears to be a stationary organism. It is multicellular. The algae is shaped like a ribbon but forms bricks over time. It is photosynthetic. There are numerous Fragilaria spotted in my micro aquarium. They are mostly found around the plant that has been placed in the water.

Cyclops pictures

The cyclops have already been covered on this blog, but I thought I would post these additional pictures. The one on the bottom is very interesting. It is of a female cyclops with egg sacks. You would never think or realize organisms like this are present in the water we swim in. Very interesting
