This 100x photograph features a liverwort (Lepidolaena taylorii) plant showing modified leaves (water sacs), which are often home to aquatic microorganisms such as rotifers. It received an honorable mention in the 2015 Nikon Small World Photomicrophotography Competition, which recognises excellence in photography with the optical microscope and was taken by Susan Tremblay of the University of California, Berkeley, using a brightfield technique.
