Coccolithophore cells are covered with protective calcified (chalk) scales called coccoliths. Coccolithophores, or coccolithophorids, are single-celled organisms which are part of the phytoplankton, the autotrophic (self-feeding) component of the plankton community.

What are coccolithophores?
The best-known haptophytes are coccolithophores, which make up 673 of the 762 described haptophyte species, and have an exoskeleton of calcareous plates called coccoliths. Coccolithophores are some of the most abundant marine phytoplankton , especially in the open ocean, and are extremely abundant as microfossils, forming chalk deposits.

Coccolithophores are marine unicellular haptophytes that possess calcified scales called coccoliths. They are classified primarily on the morphology and crystallography of the coccoliths. This classification is well supported by molecular genetic results; however, a...

Jan 1, 2017 · Coccolithales and Isochrysidales are coccolith-producing lineages that are representative of haptophytes. Approximately 200 living species are known as coccolithophores (Winter & Siesser, 1994), and many more fossil species have been described.
Phaeocystales. Isochrysidales. Coccolithales. Haptophytes are a phylum of algae, sometimes called the Prymnesiophyta. [1] All or most of them are single-celled photosynthetic phytoplankton . The cells typically have two slightly unequal flagella and a unique organelle called a haptonema.
