Quinqueloculina is a genus of foraminifera in the family Miliolidae.

Reticulomyxa is a monospecific genus of freshwater foraminiferans. The type species is the unicellular Reticulomyxa filosa. It is found in freshwater environments as well as moist environments, like decomposing matter and damp soils. The heterotrophic naked foraminiferan can feed on microbes as well has larger organisms and is able to be sustained in culture by supplemented nutrients such as wheat germ and oats. The large, multinucleate foraminiferan is characteristic for its lack of test and named for the network of connecting pseudopodia surrounding its central body mass. The organism has un

Globorotalia is a genus of foraminifers belonging to the family Globorotaliidae.
