    :cthulhu: :cthulhu: :cthulhu: :cthulhu: :band: :heart: :snorkel: It seems it is a dangerous business to view such a mating process. I think I have observed some of the same fumbling in the human rhelm. Perhaps a longer foreplay is not that alARMIMG considering the female species of any animal seems to enjoy this ritual. :D :D :D :D 8) 8) 8)
    I hope this is not too inkcredable to imagine this line of thinking, but I found the article rather humorous :lol: :lol: :lol: Sometimes I have mind pictures that go where no man has gone before :oops: :oops: :oops:
    Thanks for the article I found it interesting :shock: :shock: :shock:

    Ummm -- why does this thread remind me of something Colin once posted about a typical Glasgow pub on Saturday night?

    Yes friends, blue ring octopus. I know there exist 3 species:
    H.fasciata ( my favourite)
    H.lunalata
    and H. maculosa

    But yesterday I have seen another specie ( I can't find now the web page, sorry), it has the blue rings in a middle sice between H. lunalata and H.maculosa. What specie is it? there exist other species?

    Cheers

    H. nierstraszi, as far as I know, only exists as a preserved specimen from the Andaman Islands. There are several undescribed species. I have posted photos of one from Lizard Island and there is another very similar to H. lunulata in Lembeh. Norman also has photos of several undescribed species from Australia.

    I thought (from my brief reading of Cephalopods of the World) that there were loads of species of Hapalochlaena making it very difficult to tell the difference , and they were just numbered 1-5(other than the ones mentioned). It looks like they have only very recently speciated- I wonder if they can interbreed at all?

    Microdistribution of tetrodotoxin in two species of blue-ringed octopuses (Hapalochlaena lunulata and Hapalochlaena fasciata) detected by fluorescent immunolabeling
    Becky L. Williams, Michael R. Stark, Roy L. Caldwell (pdf) 2012

    I had to laugh at the reference to "octopamine", Looking it up (see link), it appears to have been named because it was first identified in the octopus and may have something to do with aggression.
