This week I focused on documenting more organisms. I spent more time looking at the algae in my aquarium, as this fell in place with the content we have been covering in Lab and class.
I was most excited to spot the, once-mysterious, Phacus alga again. I was able to record a video of this organism. It was quite hard to follow and keep in focus with the microscope and camera.
The organism to the left was another slower moving organism I observed this week. It is an amoeba, that has consumed other organisms, nutrients, etc. Its movement was most interesting. It morphed shape, slowly moving through my aquarium. I would like to find another example to record a video.
This video below shows an example of a Difflugia sp. It is a kind of small amoeba with a shell exterior. This was much easier to film than the Phacus, seen above.
Finally, I was able to observe another new organism this week. It had a clear body, and moved like a snake through the aquarium. I was surprised to see this for the first time this week, as I have been watching the aquarium for 4 weeks now, and this organism was larger. It was sized similar to shelled rotifers, as I recall. It is pictured below:
