Distribution: Neogloboquadrina pachyderma left coiling is nearly restricted to cold water masses, and is very often the only planktic foraminifer in Antarctic and Arctic waters. Antarctic specimens can withstand high salinities (in excess of 80), and may live in small channels within the ice (Spindler and Dieckmann, 1986).
