With Nikon about to announce the winners of the 2015 Small World Competition, we thought we'd round up some of our favourite entries! The competition includes some of the best microphotography images from around the world, giving us the opportunity to marvel at things too small for the naked eye to see.

While not restricted to wildlife, there are still plenty of shots of the teeny-tiny natural world. From the hairs on a beetle’s back to a baby starfish, these images are truly something spectacular.
