There are approximately ~50 extant planktic foraminifera that can be identified via their morphology, this number however does not include the cryptic diversity. Outlined below are the names of all living species of planktonic foraminifera, including the author, original name and the repository where the type specimen is stored. Follow the links in the image column to a [http://foraminiferaimagedatabase.marum.de/gallery2/main.php?g2_page=1 gallery] of each individual species and the links in the species name to a taxonomic description. The list will be evolving as the work of the SCOR WG138 progresses, in the mean time there exists several alternative lists of living species planktic foraminifera including [http://www.marinespecies.org/aphia.php?p=taxdetails&id=414700 WoRMS], [http://www.marinespecies.org/foraminifera/aphia.php?p=taxdetails&id=414700 the World Foraminifera Database (part of WoRMS)] and [http://species-identification.org/species.php?species_group=zsao&id=3&menuentry=groepen Marine Species Identification Portal]. | There are approximately ~50 extant planktic foraminifera that can be identified via their morphology, this number however does not include the cryptic diversity.

| + | |||
| + | Type specimens are those specimens that represent the key features of a species acting as the standard of reference for the name that it bears. This type specimen along with a published description (a 'type description') forms a key part of the process of designating a species under the [http://en.wikipedia.org/wiki/International_Code_of_Zoological_Nomenclature International Code of Zoological Nomenclature], they can either be the original specimen used to devise the species by the author or in the case of loss, damage, or in some circumstances unsuitability of the original can be new specimens elected to serve that purpose. Type specimens are stored at either Universities, Public collections or Museums in order to allow researchers access to them in the event of taxonomic dispute, revision or identification of a new species. | ||

| + | '''Neotype''' is a specimen that replaces a holotype that was either lost, damaged or in some instances where no holotype was designated. | ||
