These dinoflagellates were observed in pond water B during the protist lab at USF on February 7th, 2019 at around 3:30pm. This pond water was taken from the Beach at Castor in a shaded area and observed under a compound microscope. The temperature of the room was normal room temperature, maybe about 73 degrees Fahrenheit. These dinoflagellates were swimming fast so it was difficult to obtain a good video of them, but these were the best pictures I could get. It is hard to make out specifics on the dinoflagellates besides the transverse groove in the center of them and the fact that they are a yellowish color. This organism was observed at a total magnification of 40X. The dinoflagellates looks about the size a index finger nail, they are small. Observing live specimens under a microscope is honestly so interesting because you would never guess such tiny organisms exist and are in just a small reach of you.

Found in a sample of pond water from Castor Beach at USF. Refers to the small triangular shaped organisms near the bottom edge of the image, not the central large one.
Many dinoflagellates are found in marine environments but are also common in fresh water. Extremely common globally.

Very hard to see, but you can tell the species has the sharp edges that dinoflagellates usually have. Came from the water in Castor Beach at USF. Swam around the microscope slide at a moderate speed, couldn't quite capture all the specimens at once because they moved out the frame. Brownish-grey in color. Unicellular protists that can be bioluminescent, food, or toxins to the environment.

They have two perpendicular flagella. They also have a cellulose plate which is their armor. It is seen to have a greenish coloration.
Most of them are marine, but some live in freshwater. These dinoflagellates were found in the water from Castor Beach. They are the main cause for red tides. They even produce toxins, some of which are the most poisonous known.

Dinoflagellates are part of the Eukaryote Domain, algae under the SAR clade, Alveolata group. The dinoflagellate is part of the Protista Kingdom. This was found from a sample from Castor Beach at USF. The color varies, but in the image, it is yellowish, with light blue on the edges. It is unicellular and contains 2 flagella. It includes 2 interlocking cellulose plates. They include eyespots that are light-sensitive organelles. Their habitat is fresh water and water preserves. They are found all over the world.

These flowers are small and white with yellow centers. I found this one in Lettuce lake park. They have 5-6 leaves each. The stem of the actual plant was a couple feet long with about 10 flowers attached.

This White-Rot Fungus was found at Lettuce Lake Park on February, 21, 2019. It was a very sunny day, about 75 degrees Fahrenheit. This group of fungi was found on the bark of a tree log. It was easily identifiable as a part of the Fungi Kingdom because it had a mycelium. The Fungi has a circular shape, about the size of a quarter and has brown borders and lines, but is mostly white towards the center of the hyphae.
