phagocytosis
Phagocytosis () is the process by which a cell (biology), cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome. It is one type of endocytosis. A cell that performs ph ...

Recent molecular analyses place collodictyonids (e.g. ''
Collodictyon'') in a clade also containing
Rigifilida and
Mantamonadidae. This clade has been named
CRuMs and is sister to
Amorphea.
