5th and Final Observation!

So, yet again, the water level in the tank was nonexistent, however I did still get to catch some living organisms.

Let's start however with the deceased. There was a ton more dead organisms located at the bottom of the tank, attached to the leaves, and at the top of the tank ( can be explained, there was no water). Dead cyanobacteria was located at the top of the aquarium, numbering one in total and a another greenish/blue cyanobacteria at the bottom of the tank. There was numerous ( over fifteen ) algal Fragiliaria sp. lying motionless at the bottom of the aquarium (Prescott 1964).

It's ALIVE...
So, here are some organisms that were alive, still.
I found eight rotifers in total. Each were the Philodina sp. and they all moved like an inching worm, either attached to something like a plant or a glob of dirt (Patterson 1996). Three of the rotifers were found at the top of aquarium, three at the bottom, and two located on a plant near the side of the aquarium. Rotifers are actually a part of the Metazoa, which are animals (Patterson 1996). Four Peranema sp. (protist) were near the edge of the aquarium and they moved like a pro swimmer with a flagella (Patterson 1996). I saw one Actinosphaerium sp. (a protist) at the bottom of the tank, and it did not move while I was watching it (Patterson 1996). I saw seven diatoms, which are a part of the Pinnularia genus with a brownish color near the bottom of the tank, barely moving (Patterson 1996). A Vorticella appeared at the bottom of the tank, swinging its ciliate head side to side (Patterson 1996). And finally there was one Nematoda wiggling and squirming like a worm at the bottom of the aquarium near the dirt (Pennak 1989).

Alright guys, thanks for being my faithful SkittleSafari Supporters!!
