multiple fission
Quick Summary
Multiple fission is a form of asexual reproduction where a single organism divides into many new individuals. This process is common in parasitic protozoans and some free-living species. Unlike binary fission, which results in two offspring, multiple fission produces numerous offspring simultaneously.1
During multiple fission, the organism's nucleus divides multiple times, followed by the division of the cytoplasm. This leads to the formation of many daughter cells, which may not resemble the parent cell. For example, some foraminiferan and radiolarian amoebae can produce thousands of flagellated swarmers through multiple fission. This method of reproduction is crucial for rapid population growth when environmental conditions are favorable.1

The common planktonic foraminiferan Globigerinoides sacculifer, for example, can produce 30,000 swarmers at one time. Each swarmer is about 5 micrometres (0.005 mm) long. In planktonic species the parent usually loses buoyancy and sinks by shedding…
