Week 4

This observation was made on November 7th, 2013.

The microaquarium is still full of live. Diatoms have began to become one of the dominant organisms.

The organism in the picture above was identified as Pinnularia sp.(Patrick and Reimer 1966) It is a diatom. There were many others like this all around the micro aquarium. The diatoms can have a very beautiful appearance. They don't move quickly at all.

The organism above was identified as Tachysoma sp. (Patterson 2003) There were many other Tachysomas traveling around. They don't move very fast and kind of jerk around looking for food to suck up.

The microaquariums is populated by organisms too small to identify as well. More identifications and observations are to come.
