Post #2

This week, after viewing my MicroAquarium I noticed that the water level had dropped after a food pellet had been added the week before.  It now rests at about half full of water.  I also identified many organisms.  I saw small, round swimming organisms with 2 flagella attached to them.  These are called Anisonema (Patterson Figure 78 p.54). I also saw organisms that looked like blobs moving around picking up particles and digesting them.  These are called Amoeba and they use a chemical sensing membrane to pick up and drop particles because they cannot digest everything (Patterson Figure 192 p.98).  There was also an unknown rotifer in my water column.  Another organism that I found was a Litonotus that has two macronuclei and a large vacuole (Patterson Figure 287 p.133).
