The phytoplankton would therefore have had to reproduce themselves entirely, on average, 45 times a year, or roughly once a week. While there are thousands of different types of phytoplankton, there are several main categories that make up the most commonly-occurring: cyanobacteria (aka blue-green algae or blue-green bacteria), dinoflagellates (responsible for many 'red tides'), and diatoms (one of nature's most beautiful microorganisms). Phytoplankton are a type of microscopic plankton capable of photosynthesis found in oceans, seas, and freshwater, and an essential component of aquatic ecosystems. The plantlike community of plankton is called phytoplankton, and the animal-like community is known as zooplankton. Many animals, from single-celled Radiolaria to the eggs or larvae of herrings, crabs, and lobsters, are found among the zooplankton. Surprisingly little is known about evolutionary genetic processes in astronomically large populations of marine phytoplankton. Classically, study of the ecology of phytoplankton communities involves one or a combination of microscope-based morphological studies, flow cytometric cell counting, molecular surveys and/or measurement of the presence of specific photosynthetic pigments (Jeffrey, 1997).
