Cryptophytes or cryptomonads are eukaryote algae that are biflagellate and unicellular, with sizes between 3 and 50 μm, most are photosynthetic … WebCryptophytes are ubiquitous and one of the major phototrophic components in marine plankton communities. They often cause red tides in the waters of many countries. Understanding the bloom dynamics of cryptophytes is, therefore, of great importance. A critical step in this understanding is unveiling their trophic modes.
