Ashburn, Virginia, United States

Specimen: Open trap of aquatic carnivorous plant, humped bladderwort Utricularia gibba, with single-cell organisms inside.
Technique: Confocal imaging, 100x

Oxfordshire, United Kingdom

Specimen: Embryo of black mastiff bat Molossus rufus.
Technique: Stereo microscopy

Ashburn, Virginia, United States

Specimen: Single-cell fresh water algae (desmids). Composite image including, concentric from the outside: Micrasterias rotata, Micrasterias sp., M. furcata, M. americana, 2x M. truncata, Euastrum sp. and Cosmarium sp.
Technique: Confocal imaging, 400x

Staffordshire, United Kingdom

Specimen: Lily flower bud, transverse section.
Technique: Darkfield illumination, stitched images

Bethesda, Maryland, United States

Specimen: Mouse embryonic fibroblasts showing actin filaments (red), mitochondria (green) and DNA (blue).
Technique: Structured illumination microscopy (SIM) fluorescence, acquired with a 60x objective

Basel, Switzerland

Specimen: "Brother bugs." Gonocerus acuteangulatus, two hours old. Size 3mm.

Issaquah, Washington, United States

Specimen: Phantom midge larva (Chaoborus) "Glassworm." Birefringent musculature that is usually clear and colorless is made visible here by specialized illumination.
Technique: Polarized light, 100X

New York, NY USA

Specimen: Mouse tail whole mounts showing hair follicle stem cells and proliferating cells.
Technique: Confocal imaging

Caen, France

Specimen: Head and legs of a caddisfly larva: Sericostoma sp., a benthic macroinvertebrate that can be used for freshwater biomonitoring; because it is relatively sensitive to organic pollution and dies if water is dirty, it is a good indicator of water quality.
Technique: Stereo microscopy, 15x

Jimboomba Queensland, Australia

Specimen: Paramecium, showing contractile vacuole and ciliary motion.
Technique: Differential interference contrast, 350x-1000x

See The Tiny Carnivorous Monster That Just Won Olympus's Micro Photo Prize

Igor Siwanowicz's amazing photo of a hungry bladderwort takes top prize in the Olympus BioScapes Photo Competition. See the other mini marvels here.

"Humped bladderwort" may sound like something from the imagination of J.K. Rowling, but in fact, it's a real aquatic plant, found on all continents except Antarctica. It's also carnivorous--which makes it that much more Potteresque. A hapless microinvertebrate floating by the plant's miniature leaves could easily end up as bladder breakfast.

Today, the bladderwort is about to grab the stage from its more popular insect-eating flora. Igor Siwanowicz, a scientist at the Howard Hughes Medical Institute's Janelia Farm Research Campus, has just won first prize in the 2013 Olympus BioScapes Digital Imaging Competition for his photograph of the bladderwort in mid bite.

Siwanowicz's photo was one of 2,100 still images and movies submitted for the competition from researchers in 71 countries. Though he spends most of his time imaging dragonfly anatomy, he has now managed to give the little-known bladderwort the notoriety it rightly deserves. Take that Venus Fly Trap!

Other winners from this year's competition include the embryo of a black mastiff bat, a phantom midge larva, and a single-cell freshwater algae--which looks a lot more interesting than it sounds.

A series of winning photographs from the contest will be featured in exhibits around the U.S., Italy, Chile, Mexico, Brazil, Canada, Asia, and the Middle East next year. For now, see the top images in the gallery above.
