Gephyrocapsa is a genus of haptophytes.
Some species include: [1]
The Prorocentrales are a small order of dinoflagellates. They are distinguished by having their two flagella inserted apically, rather than ventrally as in other groups. One flagellum extends forward and the other circles its base, and there are no flagellar grooves. This arrangement is called desmokont, in contrast to the dinokont arrangement found in other groups. Accordingly, the Prorocentrales may be called desmoflagellates, and in some classifications were treated as a separate class Desmophyceae.
Gephyrocapsa huxleyi, formerly called Emiliania huxleyi, is a species of coccolithophore found in almost all ocean ecosystems from the equator to sub-polar regions, and from nutrient rich upwelling zones to nutrient poor oligotrophic waters. It is one of thousands of different photosynthetic plankton that freely drift in the photic zone of the ocean, forming the basis of virtually all marine food webs. It is studied for the extensive blooms it forms in nutrient-depleted waters after the reformation of the summer thermocline. Like other coccolithophores, E. huxleyi is a single-celled phytoplankton covered with uniquely ornamented calcite disks called coccoliths. Individual coccoliths are abundant in marine sediments although complete coccospheres are more unusual. In the case of E. huxleyi, not only the shell, but also the soft part of the organism may be recorded in sediments. It produces a group of chemical compounds that are very resistant to decomposition. These chemical compounds, known as alkenones, can be found in marine sediments long after other soft parts of the organisms have decomposed. Alkenones are most commonly used by earth scientists as a means to estimate past sea surface temperatures.
Thomas John Guiry is an American actor. He is best known for his lead performance as Scott Smalls in the coming-of-age film The Sandlot, which was filmed when he was 12, and his role in NBC crime drama The Black Donnellys. He has appeared in numerous high-profile films and television series, including U-571, Black Hawk Down, Mystic River,Black Irish, and The Revenant.

AlgaeBase is a global species database of information on all groups of algae, both marine and freshwater, as well as sea-grass.
Peridiniales is an order of dinoflagellates.
The Rivulariaceae are a family of cyanobacteria within the Nostocales in which the filaments (trichomes) are tapered from wider at the base to narrower at the tip.
Pyrenomonas is a genus of cryptomonad.
Onslowiaceae is the only family in order Onslowiales in the brown algae. The family contains only the genera Onslowia and Verosphacela.
Sphacelariales is an order of brown algae.
Perkinsidae is a family of alveolates in the phylum Perkinsozoa, a sister group to the dinoflagellates.
Noelaerhabdaceae is a family of coccolithophorids. Some genera include: Emiliania W.W.Hay & H.P.Mohler, Gephyrocapsa Kamptner, and Reticulofenestra W.W.Hay, Mohler & M.Wade.
Gephyrocapsa oceanica is a species of coccolithophorid. It is the type species of the genus Gephyrocapsa. The species is an important Pleistocene biostratigraphic marker.
The Chlorophytina are a proposed basal Tetraphytina clade. It is currently seen as sister of the Pedinomonadaceae. It contains the more well-known green alga and is characterized by the presence of phycoplasts.
