The subjects of my interests about microscopy changes from time to time. I have been crazy about rocks and minerals this summer. The temperature here has been dipped down to mid 40s degree F (7 degree C) in the early morning although the mid day temperature is still comfortably at mid 70s. I got to go out to collect some pond specimens for observation before it is too cold for any organism to be active. I choose different collection site, Briscoe Park Located at Snellville, GA.
The number and variety have been drastically reduced from my early summer observation. Again, I found seed shrimp (Ostracod) in my collection.

First time, I observed a dinoflagellate (Ceratium Furca). It is a flagellate protist. I can barely see the flagella because the flagella are relatively transparent.

The specimen was collected in 60 mL tube and split into a several 7 mL tubes and centrifuged in my homemade centrifuge.
