Movement of a Bacillaria colony with diatoms in advanced division states

In the colony shown in the video below (5x time lapse), two diatoms are in a recognizable division phase. In the second diatom from the top (referring to the beginning of the recording), the formation of valves is visible as a white line. In the fifth diatom from the top (referring to the beginning of the recording), the formation of daughter cells is well advanced, but the diatoms still adhere together. These diatoms separate the synchronous motion into independent sections. Synchronization can only be observed below the fifth diatom.
