    Dorsal Mantle White Spots

    A question I have asked many time but have never gotten an answer to is,

    "What are the two white oval spots about mid-way along the length of the mantle?"

    After an ID comment I started to research the spots because I had seen them on an obviously different animal and found that they are present on most species. I have seen them on several I've kept and found them on virtually 90% of the photos in Norman's Cephalopods A World Guide (sometimes you have to REALLY look but you will see them on most octos with multiple photos). I finally cornered Muctopus on the question and got an answer (sort of :grin:)

    Yep- sounds like more fieldwork is needed!

    They almost seem like areas of skin specialized for visual communication — sort of visual "speakers" perhaps.

    D, could you change this to include genes too?

    Wouldn't it be better to have a separate, gene-focused thread?

    This paper (free) talks about genetic differences between certain octopus species, particularly with respect to the one they're describing, O. insularis. It was very similar in appearance to the larger O. vulgaris, but turns out to be much further away in mitochondrial genes than expected:
    http://www.demersais.furg.br/Files/2008.Leite.O.Insularis.J.of.Molluscan.Studies.pdf

    The paper describes both the dorsal mantle white spots and arm crown spots in that species as distinct structures in common with O. vulgaris, but does not give much in the way of details.

    Thanks D!
    I'll read it more in depth (in my spare time), but it is an interesting article.

    I need to explore the articles on the main site at there looks like interesting publications there by this group.

    ARMS - reflexes

    Preliminary in vitro functional evidence for reflex responses to noxious stimuli in the arms of Octopus vulgaris
    Theresa Hague,Michaela Florini,Paul L.R. Andrews September 2013
    Full text available.
    Abstract

    The arms of Octopus vulgaris perform a number of functions (e.g. prey capture, exploration) putting them at risk of damage. Nociceptive reflexes provide one defence and as there is a paucity of evidence for such reflexes in cephalopods we have investigated this in isolated arms. The arms were removed immediately post mortem from O. vulgaris, suspended vertically or mounted horizontally and the responses to a pinch of the distal arm and application of acetic acid (0.1%–5.0%) or tap water to the tip recorded (video). Isolated arms rapidly (~ 1 s) withdrew in response to a pinch, tap water and acetic acid (threshold 1%) applied to the tip region. A “quasi-joint” formed in the proximal arm during the withdrawal response in horizontally mounted preparations. No response was evoked by sea water or gentle compression. Withdrawal responses were abolished by axial nerve cord section proximal to the site of stimulation.
    The results demonstrate that the arms are capable of reflex withdrawal to a “noxious” stimulus without reference to the brain. Neurophysiological studies in a more technically refined preparation are required to define the temporal characteristics of the reflex and to characterise the putative nociceptors (or other receptor types) and to determine if information from them reaches the brain.
