By now, life in the micro hood is ubiquitous. The green algae shown above, which I have now identified as Phacus, is very prominent, and seem to dot the landscape. Other photosynthetic organisms, namely cyanobacteria, are also very common. Two types I have identified are Nostoc and Anabaena, which is the really small filament looking strands in the following picture.


This algae looks interesting as well, but I could not identify it. It has bubbles around it, probably a mucus type layer. It always appears in these little colonies.


The lifeforms previously mentioned, Gastrotrich, Philodina, and Paremecium are still the most common animals. I did discover a new organism though, an Ostracod, commonly known as seed shrimp. I thought it was interesting that this is actually a crustacean, like a lobster, only really small. It is shown in the following picture:

The midge larvae is still alive and kicking, and I was finally able to get a picture of him. As you can see, it is relatively quite large, and has consumed a large amount of the muck at the bottom of the aquarium.


That's about all of the life in the Mirco hood, so far at least. Hopefully next week I will witness more new organisms, and maybe some interaction between species.
