The bright blue circles in this time-lapse video are nuclei moving around the cell of a foraminifera, a single-celled organism that lives in sediments on the ocean floor.

The video captures an experiment where researchers stained the nuclei with a fluorescent blue dye and tracked their movements under a microscope for two hours.

Unlike human cells, an individual foraminifera can have one or many nuclei to encapsulate its genetic material. The nuclei can even pass through narrow apertures leading from one chamber of the organism’s shell to another.

The experiment shows researchers can use fluorescent dyes to visualize the fine structures of these delicate cells. Researchers published the results in AGU's Journal of Geophysical Research: Biogeosciences.
