Observation #1

Compared to my initial observations of the MicroAquarium, I have noticed a significant growth in the amount of life within the developing empire.  The first noticeable change that caught my attention was the amount of air bubbles that had formed within the aquarium.  I attribute this occurrence to the increase of respiration of the growing organisms.

The the most exciting observation I made was the discovery of a nematode and an annelid.  I don't know what else I was expecting, but I was shocked to see them.  The annelid was the most interesting to watch.  She would wriggle around eating everything within her path.  She ripped away pieces of algae with surprising force.  I followed her as she swam down to the soil and devour its nutrients.  I also saw her poop which was funny, as poop always is...unless it's in your hair...which is still funny for other people.  Due to her transparent "skin" for lack of a better word, I could even see her digest the food she had been in-taking.  This is a species of the annelid species chaetogaster (Rainis and Russel 226) or Randall as I have taken to calling her:



    I also found a soil nematode (Rainis and Russel 233) slithering around some algae.  He didn't do much except move around slowly, but was a pretty interesting-looking organism nonetheless.  He had a pointed, transparent head and a body with a transparent coating encasing it.  This is a taster of the nematodes photo shoot:

Overall, a very successful observation session.
