Dinophyceae

Dinophyceae, also known as dinoflagellates, are a diverse group of single-celled aquatic organisms that exhibit characteristics of both plants and animals. They are a crucial part of marine phytoplankton, playing a significant role in the food chain. Some dinoflagellates are bioluminescent, creating the glow sometimes seen in the ocean.1

While historically classified within algae, their unique nuclear structure and large genomes make their taxonomic placement contentious. Dinoflagellates reproduce primarily through fission. Certain species can rapidly multiply, leading to phenomena like water blooms or red tides, which can be toxic to marine life. Some dinoflagellates produce potent toxins. Fossil evidence of dinoflagellates dates back to the Silurian Period.12
