It has been a long day, with several zodiac trips to try and collect krill for my experiments.  Not much luck with krill, but I caught all sorts of really neat plankton!  This video is a pteropod or “sea butterfly.”  It is related to snails and clams, and it uses its “wings” to swim!  In the background you can hear people who are out on zodiacs talking on the radio…that is how we communicate when we are on the boats.
