The surfaces of the chambers are covered with numerous long, radial needles, which facilitate floating in water. Globigerina, as distinguished from other rhizopods, is not benthonic but free swimming, and it is found in large numbers in plankton in warm seas. There are several tens of species, including many fossils. The shells of dead Globigerina fall to the bottom of the sea and form the principal constituent of deepwater oceanic globigerina ooze.
