Pictures were either 400x or 1000x magnification under a light microscope and from a pond sample from a light-exposed area on the University of South Florida campus. The following species is in the genus of Ceratium with its common characteristics of hollow horns and depressed ventral area.
This species of Ceratium (see videos) include a long apical horn and unequal antapical horns.
Likely might it be specifically C. hirundinella, a freshwater species, according to the second link provided and due to it being obtained from freshwater sources and also pale yellow. The fourth link suggests that the species might be either C. lineatum or C. kofoidii.
