TheGlobigerinina is asuborder offoraminiferans that are found as marineplankton. They producehyalinecalcareoustests, and are known as fossils from theJurassic period onwards. The group has included more than 100 genera and over 400 species, of which about 30 species are extant. One of the most important genera isGlobigerina; vast areas of the ocean floor are covered withGlobigerinaooze (named by Murray and Renard in 1873), dominated by the shells of planktonic forms.

Globigerinids are characterized by distinctly perforate planispiral or trochospiral tests composed of lamellar radialhyaline (glassy) calcite, with typically globular chambers and single interiomarginal aperture. Some however have multiple or auxiliary apertures, and in some the aperture is areal or terminal in location. Some, also, have keels, reinforcing thickenings along exterior angles. An adaptation to the planktonic habit is the development of long narrow spines that support a frothy buoyant ectoplasm.

The Globigerinina are now divided into these superfamilies and families:^[1]
