A brutal, vicious attack caught on film served as the winner of the 2015 Nikon Small World in Motion Photomicrography Competition.

The “attack” was a brief battle between microorganisms, in which a Trachelius ciliate gobbled up a Campanella ciliate, magnified 250x for our viewing pleasure:

The single-celled Campanella clearly didn’t stand a chance against the predatory ways of the larger Trachelius—but while the struggle was short it was more than long enough to secure Nikon’s first prize for Wim van Egmond, an experienced photomicrographer from the Netherlands. According to the Nikon Small World website, van Egmond had already scooped his film subjects from a pond, hoping to show them to someone else using a microscope. However, while viewing the critters he realized an attack was imminent—and was able to record the ciliate hunt in real time.
