    I found a picture on the internet a few days ago of a juvenile bimac with a vibrant purple eye spot. Was this photo shop or is there a certain light spectrum that will cause normally blue eye spots to glow different colors, and are they safe for the animals?

    It would be helpful if you posted a link to the picture but lighting will certainly bring out the colors and both bimac and hummelincki can display the eyespot very boldly.

    I think it is just a great pic that happened to capture the light and the eye-spot perfectly.

    You don't think there is a specific light spectrum that could turn the blue eye spots other colors like a black light or purple actinics?

    I have seen my hummelincki display just as brilliant a blue in my 55 gallon tank which only has household fluorescent lights. so no I dont believe it is lighting related.

    But aren't all eyespots blue? My thing is there has to be something making it look purple.

    Different light will produce different results.

    Are the eye spots made of iridophores?

    That is most likely not a bimac. I suspect it is Octopus mototi.

    I just google'd Octopus Bimaculatus and that picture came up and the person who posted it labeled it as such. It's a beautiful octopus none the less. So is Octopus Mototi available in the aquarium trade? Does it almost always keep that color patern?

    Mototi is Polynesian. It is apparently somewhat hazardous to people.

    How so? Are we talking Blue Ring hazardous? Where can I get more information on them?

    Late to the ballgame but the body does not look at all like a bimac but the stripe pattern does look like the pictures I have seen of Mototi. One of our member's father amazed locals by catching them only to find out later that they were poisonous (sadly, I cannot locate the thread).

    I have always thought they were deadly like the blue ring but, looking for information does not confirm or deny that understanding. Here is a nice video of one in situ. You can clearly see the stripes and ring forming when it is disturbed.

    I must say that I'm very tempted to seek out one of these little guys, though I would really like to learn more about this "poisonous" bit. That was a great video.
