Week Two Observation

On Wednesday, October 23, I observed a few organisms in my Micro-aquarium. These included a Cyclops, Pinnularia, Amisonema,Gomphosphaeria, and Coleps.

The Cyclops has six legs near the anterior of its body and a large round spot on its back that resembles an eye. When I discovered it, the Cyclops appeared to be hopping near the soil. (Pennack)

 The Pinnularia is a diatom that is rod shaped and is a golden-green color. It slowly floats around the aquarium in various areas.

The Amisonema is round and has two flagella that allow it to move swiftly about the aquarium.

Gomphosphaeria is a Cyanobacteria that forms colonies as seen in the picture below.

I enjoyed observeing the Coleps. They are oblong and brown. These peculiar organisms tumble around the tank changing their shape into a ball and expanding it again. This motion can be viewed in the video below.
