Chromatophore activation

Some information about this video - I recorded it in the summer of 2014 when I was at the Marine Biological Laboratory on a short visit to collect data for my dissertation. This animal was to be used in an experiment but died shortly before we started running our trials. I thought we should get at least some use out of the animal and started recording on the spot. The video is actually longer and we are using it to test a video analysis plugin made specifically for our studies. We are analyzing a ton of data collected over three summers and planning to publish this upon the completion of my degree in 2016
