The Nikon Small World Competition highlights the best in microscope-aided photography. Popular Science has funnelled out "the best of the unborn" from the list of 115 winners.
These cute babies are so tiny that microscopes with powers up to 630x are required to get these 'family portraits.'
The embryo images shown here are the following:
1. 9 day old chick
2. 5 day old squid
3. Mouse at 13 days
4. Embryonic earthworms
5. Rat embryo cortical neuronal network
6. Just fertilized killifish
7. Embryonic stem cells of a mouse
8. Japanese rice fish eggs
