Week 4

Once again Desmids were present in great numbers, two types were found: the Clostreiun-elongated and curved with pointed ends (pictured below) and the Starastrium- Circular and green (also pictured below). Rotifers were still found feeding in the algae. Both Colpidium and Euplotes Cilia were seen under the microscope and seemed to be everywhere in the microaquarium. This week I also found a Gastrotrich. A gastrotrich is part of the Animal Kingdom and the Gastrotricha Phylum, they use sensory hairs on their head to move and they feed off algae (picture below). Diatoms were also discovered this week near the Desmids.
