2020 Small World in Motion Competition

This movie of a microscopic Spathidium ciliate feeding on a Vorticella ciliate beautifully illustrates the relationship between hunter and predator, even in the microscopic world of ciliate creatures. A phase contrast movie such as this requires imaging skill and patience since it can take quite some time to capture a predator in such a moment and skill to be ready to capture it visually when the opportunity presents itself.
