durling's Identifications

This organism was found in pond water from a local pond on campus. This Protozoa was green and the pictures were taken at both 40x and 100x. This protist is often found in pond water and it is photosynthetic. That is the hallmark characteristic of this species. In general, protists defining characteristics are that they are eukaryotic organisms that are not plants,animals,nor fungi, but may share similar characteristics with them. This Identification was cross referenced with the BSC2011L lab manual.

-Kingdom: protist
-Identification: SAR clade - family - ceratiaceae
-Visual Description: spear like edges protruding on an oddly shaped body
-“Ceratium, genus of single-celled aquatic dinoflagellate algae (family Ceratiaceae) common in fresh water and salt water from the Arctic to the tropics.” (Britannica)
-Habitat: our sample was located in a pond on an urban university campus, specifically taken from an area exposed to sunlight. But, they are a marine/freshwater species found in various locations.
-Observed: in lab at the University of South Florida
-Defining characteristic: alveoli and cellulose plats

This is a small protist collected from a local pond. It has a small tail with two horns at the top of its head. These organisms are common protists that cause red tide.
They are found in both fresh and saltwater.

Yellowish in color. Branch like structure. Found in castor lake pond sample. Found in light side of the lake. They live in a variety of habitats which include fresh water, marine and soil. They can be found worldwide. https://eol.org

This is the picture of a protist that was taken in my Biology lab under a microscope. This
image has been cropped from a video. In the video, Euglena sp. changes shape due to the flexibility it receives from its pellicle. This single-called eukaryote can be either heterotrophic or autotrophic. They live in both salt and fresh water- aquatic environments. It is small in size, green colored, and has a stigma near the flagellum. It is involved in performing phagocytosis as well. (https://www.thoughtco.com/about-euglena-cells-4099133)

Found within aquatic ecosystems, they are one celled prokaryotes with two distinct flagella.
They range from 5-2000 micrometers in size.

Part of the Genus Ceratium, which is characterized as single-celled aquatic dinoflagellate algae.

This individual was found in a fresh water pond (freshwater habitat).

Geographic distribution is along the coasts in the United States.

This organism was observed under a microscope at 400x magnification and was grey in color. I believe that this is a Dinophysiaceae because of its triangular shape and thin legs. The organism was found in a shaded region of a pond in the University of South Florida campus
https://eol.org/pages/4758
found in marine environments around the world

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"

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
