Week of Oct 25-31
Since the food was inserted into the aquarium the life forms have began to multiply! There were many things found this week such as Rotifers, Peramiciums, Green Alga, Gastrotriches, and many others. The Rotifers mastax seems to pulsate like a rapid heart beat. The mastax is a structure that is peculiar to the digestive system of the rotifer. There is no known comparable device in the animal kingdom, It has the appearance of a bulbous swelling that is in between the pharynx proper and the esophagus. The mastax consists of a complicated arrangements of muscles that activate a set of translucent jaws called trophi which are used to seize, tear, grind and macerate the food that it takes in.
The bigger organisms that were found are populated around the food pellet waiting on the smaller ones to come in to eat and they will take advantage of that and eat them.
Plant A has shown signs of growth.
The Gastrotriches that were found are worm like and brows on the substrate. They ingest bacteria, algae, small protozoans, and organic detritus. They are long cylinder muscle like organisms. The Gastrotrich has sensory receptors on their head. The function of these sensory receptors is not known. The Gastrotrich produces 1-5 eggs in its life time and the lifespan of the Gastrotrich is 3-22 days. All are parthenogentic females and males are unknown.
All information concerning life forms in the aquarium was found in:
Fresh water invertebrates of the United States 3rd edition, by Robert W. Pennak which was published in 1989 by Willey-Interscience Publication.
