roman-evseev's Identifications

Observation Description:
This organism is a Dinoflagellate (Phylum Miozoa) and it belongs to the Kingdom Protista. While searching under the microscope, we came across a protist that resembled the shape of a sea shell. It was microscopic in size, and seemed to have two flagella. Its color was light green and yellow. It also contained white color in it as well. The characteristic that determined that it was from the Kingdom Protista was its microscopic size and two flagella. It seemed to have a hard shell which represents its cellulose plates. According to Wikipedia, dinoflagellates are unicellular and possess two flagella. They have cellulose plates that act as protective armor. Half are photosynthetic and the other half are heterotrophic. They tend to be responsible for the red tide. They form mutualistic relationships with coral. They acquired the ability to photosynthesize through secondary endosymbiosis of a red algae (Source: Wikipedia).

Location, Habitat, and Distribution:
I observed this organism in my biology lab. According to the TA, a sample was taken from a pond at the University of South Florida. It was collected from a portion of Castor beach that was exposed to sunlight. Lat: 28.063082 Lon: -82.411015. Their habitats include all aquatic environments such as marine, fresh water, ponds, and even snow or ice. They are distributed almost anywhere there is water. They are abundant in both marine and freshwater environments (Source: Wikipedia).

Kingdom Protista

Water sample collected from the shady area of a pond on the University of South Florida campus. Possibly Genus Ceratium (it the upper left hand edge of the water sample) and Genus Micrasterias (indicated by the black pointer) present in the sample.

This was looked at under a microscope in a lab environment. The looks of it make me believe that it is a Ceratium because of the fact that it has a horn, two flagella, and what look like armored plates. https://www.britannica.com/science/Ceratium

Microscopic organism observed at 400x total magnification. Diamond shaped body with 3 skinny appendages. I made this classification with the help of the following website
https://en.wikipedia.org/wiki/Ceratium
It states of the organism that "most species of Ceratium are unicellular organisms that are characterized by their armored plates, two flagella, and horns. Species of Ceratium are found worldwide and are of concern due to their blooms"
