I finally was able to capture a stubby squid (rossia pacifica) changing color from reddish purple to iridescent. 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.
From The Cephalopod Page:
The Stubby squid, Rossia pacifica, is a member of the sepiolid family of cephalopods. Although sepiolids are commonly called squid, they are not true squid. They look like a combination between octopus and squid but are actually more closely related to cuttlefish. Like cuttlefish, they can bury themselves in the sand. Like octopuses, they mostly live on the bottom rather than swimming in the water. They have eight suckered arms and two long tentacles like squid, but don’t have a quill or cuttlebone for internal body support. They swim by using the fins on either side of their body or use jet propulsion by taking water into their body cavity and squirting it out a funnel.
