    Hi there

    Could you any one help me to identify this octopus. I took the picture at Jones Bay, Tawharanui Peninsula which about 60km north from Auckland. I would like to know which species of this octopus. I try to find from guide book but it is very confuse... I think ether Octopus gibbsi or Pinnoctopus cordiformis.

    size: head 14cm leg 46cm total 60cm

    He was in the Rock crevice at 2m deep water. Water temperature was 19 degrees. I took this photo at 19th April 2010.

    Coming from the othere side of the world and just learning to ID them I'm still a slow at finding identifying parts. I didn't think O.gibbsi showed the skin tabs like on our GPO but looking at [video]http://www.tonmo.com/forums/showthread.php?18734[/video]of a group of suspected O.gibbsi, there is one photo where you can see the same look on what looks to be similarly sized animal. The other O.gibbsi suspect thread is of smaller animals. Did you get a photo of the underside? Both threads show VERY orange undersides. I don't see the tell-tail white dots of the P.cordiformis.

    Rereviewing the pictures, I don't think O.gibbsi as there is an exposure of the inside of the arm in the swimming photo and it shows white. One of the problem with using color though, is that it is not consistent. O.gibbsi may be able to show a white underside (I know O.hummelincki can show peach or white) but none of our in situ photos shows anything but very, very bright orange.

    Not P. cordiformis, I'd go with O. gibbsi

    Did anyone notice something odd about the next to the last photo? Look at the eye/iris. That photo does seem to show orange around the suckers and looks very much like the other O. gibbsi pictures.
