These two shots are I believe of the closely related mototie octopus. There was 21 secs between the shots and it changed faster than that when irritated by the dive guide. About 2-3 inches long delightful little beastie.

Nice picts Tim. The red and brown is the "normal" chromatophore system at work. As it is directly controlled from their brain, they can change colors in fractions of a second. The blue eye spot is from iridescence, a different system.

We sometimes see a similiar stripped pattern in swimming O. vulgaris (common octopus) in the Caribbean. I think it may mimic a local parrot fish.

Interesting topic - scientist do the work and write the ms and also review them but publishers claim copyright. Of course, without publishers most ms would not see the light of day but that is changing.

With PDFs the publication and distribution costs are much lower. Newer fully online journals allow scientists a lot more liberty to share their work. Also some journals now have blind reviews - another step in the right direction.

My work focuses primary on cephalopods and as much as possible (Exa. I post my work until someone complains) is available online here: http://www.thecephal...rg/JWood/cv.php If you are suffering from insomnia, I highly recommend my 300+ page thesis. . .

Unfortunately the image links appear to be broken - I'd really like to see your images.

One thing I would be looking for is if the red color appears metallic. As far as I know, cephalopods are not fluorescent (absorbing one color of light and re emitting it as another) but are iridescent (differential refraction of light). The red anemone at 100 feet as well as the colors of many corals under uv light are great examples of fluorescence. The metallic color of many insects, especially certain metallic blue butterflies, is a good example of iridescence. Soap bubbles and oil on water are also examples. Iridescence is directional - change your viewing angle and the colors you see likely change. Color from pigments (most things) and from iridescence doesn't behave like that.

Cephalopods also have an iridescent system that is separate from their better studied chromatophore system. Unlike buttefly wings which are fixed, cephalopods can turn there iridescent system on an off!
Both iridescence and fluoresce can be very difficult to photograph. For iridescence you generally need to be shooting available light. What you see is not what you get when your strobes chance the angle and properties of the incoming light. For fluorescence, you may need to shot available light (its dim at 100 ft) or supply the “right” spectrum of light (often uv) and add a filter to your camera to block undesirable noise.

You might want to just switch to the Eye of Mine housing.  It improved things greatly.   I have a friend who now uses it in a Sartek housing and likes it but I personally have not tried that.d
Steve

How does the GoPro in an Eye of Mine housing compare to a Flip HD or JVC camera in an Ikelite housing?

James

Hey James, yes, not gonna happen, a new camera will most certainly require a new housing. Congrats on the move to Hawaii by the way!

My 20d has died.  Looks like it is time to upgrade. . .  Drat.

On the plus side, there will be plenty of chances to use an UW camera here!  Thanks for the replies.
