This organism was found in pond water from a local pond on campus. This Protozoa was green and the pictures were taken at both 40x and 100x. This protist is often found in pond water and it is photosynthetic. That is the hallmark characteristic of this species. In general, protists defining characteristics are that they are eukaryotic organisms that are not plants,animals,nor fungi, but may share similar characteristics with them. This Identification was cross referenced with the BSC2011L lab manual.
Found at the USF pond in the shallow part of the lake. Its is a protist that can photosynthesize.
Mag. 400x
Small flagellate with a probing "nose". My scope could not resolve the critter cleanly, but it was fun to chase, after it swam into my field of view. (The 2nd image shows the small, inconspicuous, shadowy figure as it appeared in the 400x field.) I could only see it for a short interval before I lost the ability to track it.

Collected with permission from a relatively large pool in a Granite Outcrop that almost always contains water. pH of water was 6.65 when collected. 1000x Lots of cilia visible. It never stopped moving while I was observing it. It mostly spun around in lazy circles.
Observation is from a small sample of water taken from a quillwort pool on a Granite Outcrop with permission from the site managers. pH of the water was tested and was 6.60. 1000x
