Newsvine's resident conflict moderator captures a great series of photos which depict a "Stubby Squid" as it changes color.
The small (3″) squid held its pose for just long enough for me to snap a couple shots. They typically change to the lighter-pale iridescent colors when they feel threatened. My dive light gave little squiddy just enough of a scare to change his color for a fraction of a second, but not enough to make him flee.
Congrats on the capture!
