observation 2; week of October 27th

This week i saw a few of the same rotifers from last week, including several Euchlanis macrura, but i saw a new organism. I identified the organism with "Guide to Microlife" as being in the genus Halteria. It is a Protist that is found in ponds, bogs, and open waters, and it is much smaller than the rotifers.  This organism was transparent, therefore most of its organelles were visible under the microscope.  It has a round body with a groove at the top of its body and it bounces around very quickly. It has groups of three long, pointed cirri around the mid section of its body, and a group of fairly long cilia around its mouth.

When I went and observed my micro aquarium, I noticed many interesting things which I have never seen before. There were several different kinds of amoebas. One type looked like a blue blob that kind of oozed around and changed its shape.  The other one was a circular organism called Actino sphaerium that had a large amount of prickly hair looking appendages protruding from its body in every direction. The majority of the bacteria I saw were various types of rotifers. One of them was Noleus quadricornis and it was somewhat round. It had one tail/flagella and most of its head was covered in cilia. Another one was Euchlanis macrura and it was very similar to the first rotifer, expect that it had two tails/flagella. One resembled Ritifer citrinus and it was much different from the other two. It was long and slender and had two clumps of cilia at each end of its mouth.

In my microaquarium, I used water source number 10. I wanted to make my microaquarium interesting and diverse, so I inserted a number of different water plants and a good bit of soil, which contains bacteria and various organisms. The plants that I inserted were plants A and B, and I am anxious to see how my microaquarium will be changed by next week.
