Emiliania huxleyi is a calcareous alga and belongs to the order of the Coccolithophorida . It occursworldwidefrom the polar regions to the equator and is a key species in the ocean ecosystem. Coccolithophores such as Emiliania huxleyi account for almost 50 percent of the ocean's biological carbon pump and account for a third of the ocean-bound production of calcium carbonate .

Emiliania huxleyi is a unicellular phytoplankton covered with microscopic calcite discs, so-called coccoliths. Named after the British researcher Thomas Henry Huxley , Emiliania huxleyi is the world's most important representative of the coccolithophorida.

Algal blooms of Emiliania huxleyi can reach enormous proportions, possibly up to 100,000 km ² .

Emiliania huxleyi was voted Alga of the Year 2009 by the German Botanical Society due to its climatological relevance .
