Observations from 10-24-07

The first organism to catch my attention today was a rotifer that was attempting to catch lunch. The meal was some sort of one celled creature, much smaller in size than the rotifer. The most interesting part of the encounter between the two creatures was the movement of the mouth parts of the rotifer. These parts were spinning and creating a small current trying to suck the prey in. Not sure if the rotifer won. Some of the other more interesting organisms observed today were Actinopods and Annelids. The annelid looked almost identical to a snake. Also, an interesting organism called a carpenters ruler was observed. It was hard to figure out what it was doing, but its movements looked very mechanical and pre-determined. Aside from the more animal like creatures, it appears some small plant life is sprouting at the bottom of the aquarium and off of some of the sediments.
