Monday

This week I have seen more interesting organisms than in weeks before. For instance, the Peranema to the right ingests food with the use of two ingestion rods(Patterson 210). There is clear visible movement of the flagella. The flagella mostly stays straight with the end twirling in search of food. It was also common to see more than one organism at any point. Between cilliates, amoebas, different flagellates, rotifers and many other organisms, I am suprised not to see any organisms feeding on other organisms. If I ever see it happening I'll be sure to get a picture of it. The amoeba above is one of the many that I saw. They have very colorful organelles which are free floating inside the amoeba. With very slow movement they stretch out their pseudopods and dragging itself along the aquarium wall. A final video I have shows a Rotifer in feeding. The feeding structure called the corona is outlined with ciliated tufts which create a current that brings food into the mouth ("Rotifers"). As you can see in the video, these rotifers can be startled as I tapped my pencil on the aquarium, very interresting.
