Notes & discussion: C. pelagicus is a very widespread, long ranging, and diverse species which could probably be usefully subdivided.
Extant sub-species
Two discrete morphotypes of C. pelagicus have been documented in the modern nannoflora (e.g Cachao et al. 2000), culture studies and molecular genetics have shown that these are genotypically discrete but very closely related. They are variably distinguished as sub-species (Geisen et al. 2003, Young et al. 2003) or species (Saez et al. 2003).

Palaeontological variation
Coccolithus is highly variable in the Neogene although only C. miopelagicus is regularly regarded as a discrete species. Note in particular that:
1. Forms with well-developed bridges only occur in the Late Pliocene and Quaternary
2. C. pelagicus largely disappears from low latitude waters in the Early Pleistocene.

Distinguishing features: Elliptical placolith coccolith with central area open or spanned by a disjunct bar on the proximal surface.
