swarm cell

In biology, a "swarmer" refers to a motile, often ciliated, stage in the life cycle of certain organisms, particularly protozoans. These swarmers are typically produced during asexual reproduction and are responsible for dispersal. For example, some sedentary protozoans, like the suctorians, reproduce by budding, creating ciliated swarmers that detach and find new locations to settle and develop. Similarly, foraminiferan and radiolarian amoebae can produce many flagellated swarmers, or zoospores, as part of their multiple fission reproductive cycle. In the context of beekeeping, a swarm is a large group of bees, including the queen, that leaves an established hive to form a new colony.12
