Nikon unveiled the winners of the 40th annual Nikon Small World Photomicrography Competition yesterday, with a contributor from Panama taking home the competition’s top prize with an image of a microscopic rotifer’s open mouth interior and corona.

In all, Nikon gave awards to 80 photographers and scientists for their work in photomicrography, which is a digital image taken through a microscope of an object that would be much too small for the naked eye. You can view all the winning images on the competition’s website here.

Rogelio Moreno, who won the first-place price, was able to capture a rarely seen shot of a rotifer’s open mouth, and the judges praised him for using flash to freeze movement as soon as the mouth opened, a window which would have only lasted one or two seconds.

Nikon also gave out honorable mentions to 10 other photographers and scientists, and will exhibit the top images in a full-color calendar and with a tour through museums around the nation.

Images included ones of a jumping spider’s eyes, a house cricket’s tongue, a caterpillar proleg, a brine shrimp’s appendanges, parsley, and even cells from a cow’s pulmonary artery.

A photomicrograph is typically prepared with an optical microscope, or sometimes more basically by simply attaching a camera to a microscope.
