Posted on February 7, 2012
A water flea (Daphnia) plays with a volvox (a type of green algae which forms spherical colonies) in this video. The video - taken by Dr. Ralf Wagner - took third place in 2011 Nikon Small World in Motion, a photomicrography competition. Take a look:
First place in the competition went to Anna Franz, for a video of an ink injection into the yolk sca artery of a 72 hour-old chick embryo.
Dr. Dominik Paquet took second for a time lapse movie of mitochondria in nerve cells of transgenic zebrafish.
There were also eleven fascinating honorable mention photomicrography videos. These videos below were all given an honorable mention by Nikon.
