Tiny Critter Becomes a Big Wheel

An extreme close-up of a type of rotifer known as Floscularia ringens has won first prize in the 2011 Olympus BioScapes Digital Imaging Competition, which showcases photos and movies of life science subjects. The image was the top selection out of more than 2,000 entries in this year’s contest — and it earned the photographer, Charles Krebs, $5,000 worth of Olympus imaging equipment.
