10 incredible images of the tiny world around us

These are the winners of Nikon's 'Small World' competition.

There are plenty of large, incredible things in this world, from canyons to oceans and huge fossils left behind by dinosaurs. But most of the things that make up our wide world are small--tiny even. Often, these things escape notice because they are simply to small for the human eye to see. Which is where Nikon's annual Small World competition comes in. Every year a panel of judges selects the most stunning images of very small things. Often, the people who capture these images are scientists, who come across these stunning images in the course of their daily work. Nikon received over 2,000 submissions from 83 countries for this year's competition.

Third Place: Bladderwort
Open wide! This is the intake, or entrance to the interior of a bladderwort, a carnivorous freshwater plant. The plant sucks prey into its trap, where it becomes a tasty meal. But don't worry, it isn't Audrey II. This little guy is less than 2 millimeters long.Igor Siwanowicz
Fourth Place: Mammary Gland
Fourth Place: Mammary Gland
The pink blob in this image is a lab-grown human mammary gland organoid. Researchers have grown breast tissue in the lab to better understand how cancer forms, and also how mammary glands originated.Daniel H. Miller & Ethan S. Sokol
Fifth Place: Brain Tumor
Fifth Place: Brain Tumor
Researchers imaged this picture of a growing glioblastoma (brain tumor) in a mouse. The red 'netting' surrounding the tumor is part of the mouse's vascular (blood supply) system.Giorgio Seano & Rakesh K. Jain
