Blue Ringed Octopus juvenile , Hapalochlaena maculosa,
Edithburgh Jetty night dive, Yorke Peninsula, South Australia.
Please note that at no point was this octopus touched, goaded or coaxed into going up in the water column. It was an atypical response to closeness of divers. Discussion about Octopuses photographed midwater- wetpixel.com/forums/index.php?showtopic=23452
I was photographing this tiny BRO which was found in Sagassum weed about 0.5m from the bottom. It launched itself off the weed then drifted to the bottom to escape my attention.
