MicroAquarium Week 4

This week when looking at my microaquarium I saw two Vortecellia, which I haven't seen in the previous weeks. Also, I noticed when observing my microaquarium that the other bacteria had grew and it also looked like the numbers in the bacteria increased.

"The Vorticella is a protist (protozoan) and belongs to the Phyllum Ciliophora.  It is a very interesting, stalked ciliate with an inverted bell shape.  The stalk contains a contractile fibril called a myoneme.  When stimulated, it shortens, causing the stalk to coil like a spring" (Microbus, 2003)
