The Globigerinina is a suborder of foraminiferans that are found as marine plankton.

They produce hyaline calcareous tests, and are known as fossils from the Jurassic period onwards.

One of the most important genera is Globigerina; vast areas of the ocean floor are covered with Globigerina ooze (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 radial hyaline (glassy) calcite, with typically globular chambers and single interiomarginal aperture.

An adaptation to the planktonic habit is the development of long narrow spines that support a frothy buoyant ectoplasm.
