Observation 3 : PROTOZOA

One grain of beta food has been added to the aquarium  two days before this observation.
Observation: PROTOZOA (single cell)
4 types:
Lacrymaria
Anisonema
Euplotes
Vorticella

after looking around for about 20 min. I found a large grouping of protozoa near the beta food grain. The only that were clear enough to id were the four mentioned above described here:


Lacrymaria: spindle shaped cells with a long highly mobile neck supporting a rounded mouth at the end (Patterson 1992).

Anisonema: have two flagella that vary in size
                  anterior flagella: the shorter of the two that beats at a normal pace(Patterson 1992).
                  recurrent flagella: the longer of the two that trails along the "ground" , can jerk the cell back and
                                             forth(Patterson 1992).

 Euplotes:  characteristic form of flagella present for movement. (Patterson 1992).

Vorticella Campula: Flagella used for propultion but mostly for anchor (Thorp 2010)
