    Globigerinoides sacculifer exhibits two different morphologies, known as G. sacculifer with sac and G. sacculifer without sac. The sac feature is a sac shaped terminal chamber that is formed prior to the production of the gametogenic calcite.

    Commonly used species include G. ruber, G. sacculifer, G. subquadratus, and G. altiaperturus . Globigerinoides sacculifer exhibits two different morphologies, known as G. sacculifer with sac and G. sacculifer without sac. The sac feature is a sac shaped terminal chamber that is formed prior to the production of the gametogenic calcite.
    Globigerinoides sacculifer (Fig. 16) is abundant in tropical water masses. Clear relationships of relative abundance with sea surface temperature and the temperature at 200 m depth exist. The species has narrower tolerances for summer conditions in these parameters, surface water density and the vertical temperature gradient.
    Globigerinoides sacculifer subsacculifera Cita, Premoli Silva & Rossi, 1965 was erected for specimens of similar gross morphology to T. sacculifer, but possessing a smaller test and less-developed sac-like final chamber. The last chamber is elongated, but not as pointed and protruding as in T. sacculifer (Cita et al. 1965 ).
    Globigerinoides, on the other hand, has a ruber - or ruber / sacculifer type wall texture (Spezzaferri et al. 2015 ), which is cancellate but less symmetrical than the sacculifer -type wall texture (see Hemleben & Olsson [ 2006] for full distinguishing features and illustrations).
