The taxonomic classification system (also called the Linnaean system after its inventor, Carl Linnaeus, a Swedish botanist, zoologist, and physician) uses a hierarchical model. Moving from the point of origin, the groups become more specific, until one branch ends as a single species. For example, after the common beginning of all life.

Classification. The higher classification used in this catalogue follows, as far as possible van Nieukerken et al., 2011. In: Zhang, Z.-Q. (Ed.). Animal biodiversity: An outline of higher-level classification and survey of taxonomic richness'.
A coccolithophore (or coccolithophorid, from the adjective) is a unicellular, eukaryotic phytoplankton ().They belong either to the kingdom Protista, according to Robert Whittaker's Five kingdom classification, or clade Hacrobia, according to the newer biological classification system.Within the Hacrobia, the coccolithophorids are in the phylum or division Haptophyta, class Prymnesiophyceae.
Coccolithophore. Coccolithophores are one of the main types of phytoplankton in the ocean and their production of calcium carbonate significantly diminishes the effectiveness of the biological pump for sequestering carbon dioxide (CO2) in the deep ocean.
In these two Key Stage Three activities from the ARKive collection, students learn about why species are classified, the ways in which this can be done and the key characteristics of mammals, birds, reptiles, amphibians, fish and insects. In the first activity, students play the Guess Zoo game to help them understand the differences between different types of animal.

Abstract. Electron microscope observations show that the coccolith ofCoccolithus huxleyi is composed of radially arranged units, each consisting of an upper and lower element and a central wall. From the results of electron diffraction analysis the whole unit is considered to be a single crystal of calcite having the form of a hollow crystal.

Coccolithophores, a diverse group of phytoplankton, make important contributions to pelagic calcite production and export, yet the comparative biogeochemical role of species other than the.
The coccolithophore Coccolithus pelagicus (Wallich) Schiller fixes CO2 into particulate organic carbon (POC) through photosynthesis and into particulate inorganic carbon (PIC) in the form of calcite. To examine the role of phosphorus (P) availability in the production of POC and PIC, C. pelagicus subsp. braarudii (Gaarder) Geisen et al. was grown in semi-continuous cultures at three initial.
