    I posted this video on TONMO, but I'm not sure how you find it, so I'm also providing the YouTube address.

    During our recent work on Lizard Island (North Queensland) we caught three of these small bottletailed squid. The smallest was 1.5 cm and the largest just over 2 cm. All three were taken at night (no moon) using a dive light. They were from sandy areas with patch reefs (1 - 17 m). I don't recall collecting this species before, but they were apparently common this August.

    Like many sepiolids, they employ two arms to bury themselves in sand, but couple this with blasts of water from the funnel fore and aft. Also, when exposed they assume a characteristic orange color, but as they bury in the sand, they turn black and white.

    That's more efficient than most cuttlefish I've seen.

    Mucktopus,

    Two large male and two large female A. aculeatus at extreme low spring tide at Coconut. Nothing else except these Sepiadarium kochii.

    I've attached another video clip of Sepiadarium kochi burying itself in sand. Here you can see both the jets of water being jetted below the animal and the use of the arms to throw up sand.

    These rate a 10 on the Braid Index!

    (This index for cuteness will appear in Chapter 2 of my thesis.)

    Wow, these videos are fantastic. Thank you for posting... now Heather Braid is whining about how she wants us to get one as a pet... there goes all my savings!

    Great videos. I'd like to see a comparative study across cephs on this "fixed" behavior. Similar to Jennifer Mather's study, see which phenotypes fare better at this when different substrate is used.

    Starvos, do you have a link to Jennifer Mather's study and is it specific to octopuses?

    Here's a link to 3 different sources. Send me a PM if you can't get it and I'll send you the article. As you can see, the study was done with cuttlefish.

    Thanks Starvos, the article would be a good thing to examine for keeping some of the exotics but I was hoping for more of a preference definition for octos. I have noticed that the octos I keep will remove the argonite from their den areas if they choose a ground level den (and have two rather humerous videos of sand rearrangement by senescent animals) and was hoping for a substrate of choice type article. I might have to experiment with a bare bottom tank to see if an octopus would be out more offen without sand - you have definitely started me thinking :grin:. I wonder if I can clear a section of Little Bit's tank :hmm:

    Amazing! Our Sepioloidea pacifica shows similar behaviour, but I've never been able to capture it on tape!

    Roy,

    I was working on some video from this summer and found this, and thought of this thread. Pretty sure its the same species.

    Looks like it. Great video. It is amazing how little we know about these animals.

    That is the strangest behavior I think I have ever seen, great video!
