Heliozoa. Plasmogamy.

Sometimes we observe the Heliozoan division process in which an individual divides to form a new Heliozoan. In this video we observe the opposite process, that is, two individuals come together to form a single individual; Fusion / fission?

Nice! Is this a sex process as in conjugation?

Excellent and fascinating video, Francisco! This process is called plasmogamy, in which two cells can fuse into one. The cells fuse their respective cytoplasm and nuclei. I saw this in the heliozoan Actinosphaerium, as shown in the photo below.
