Week 4

On November 5 I observed:

I was able to identify lots of new stuff.

  • Tachysoma, which have cirri to help them move and have a spastic jerky motion.
  • A shelled rotifer hanging out next to the dirt.
  • about 5 Amoebas. These look like slime moving around
  • some Arcellas, Mayorellas, oscillatoria and protcoccus
It appears that I am seeing a wider variety of organisms but it is possible that they were there all along I just missed them. While I am seeing more kinds of organisms the population of the organisms no longer seems like it is increasing like last week. There are less rotifers than last week possibly because the food supply is being exhausted and can no longer support their large numbers
