    that's what we saw on the beach, but it was bluer, not purpleish.

    You're just hoping that I suggest that you be Carla.

    Look, if you want to become Carla, become Carla,
    you don't need my permission.

    Sorry Orleander
    /back on track.
    I promise to get some photos of bluebottles in the next month or two.
    They are actually really beautiful and the ones I see are blue with a purplish tinge.
    They are often accompanied by a little critter called Glauca atlantica which is a similar colour. I thought I'd found one of these the other day but it turned out to be a tiny free swimmimg crab with amazing blue/purple eyes ( never seen one of these before)

    Glauca Atlantica is a tree. And a bloody good one.

    Wow!

    It's all in the details isn't it?

    Here's Glaucus atlanticus

    Your tree is Cedrus atlantica var. glauca

    It seems the Glauca refers to that lovely blue/ grey colour.

    p.s There are many Eucalypts which have this colouration in the form of a waxy bloom which helps them in extreme weather conditions.

    A Sea Slug.
    Amazing looking creature.
    It is like a costume from the Rio Carnival.

    I found this while looking for it. Patterns generated in a ferrofluid by a magnetic field.

    do those things sting? What is their defense?

    Harmless as far as I know. I've held them in my hand before. Amazing things.
    I would guess their defence is looking a little like stinging jellyfish ( colour of bluebottles).

    Box Jellyfish has 24 eyes.



    The box jellyfish, Tripedalia cystophora, a cubozoan, is a bizarre, highly poisonous predator .
    "These are fantastic creatures with 24 eyes, four parallel brains and 60 arseholes," says Dan Nilsson, a vision expert from the University of Lund in Sweden. (Source: New Scientist, 8 November 2003, p. 34)


    The following article says they have no brains at all. But surely to see, you need a brain.

    Wow!
    Big news Orleander... These guys are great, Glaucus atlanticus actually feed on the bluebottles ( they are immune to the venom) but can store the venom in their "fingers" and inflict an even more painful sting than the bluebottle. I'll be more hesitant to handle them next time.

    Yes, they are a form of sea slug (gastropod molluscs).
    I'm pretty sure I've eaten sea slugs in Fiji but they may have been sea cucumbers, they were collected and cooked by locals and I devoured them with glee..delicious!

    I was handling some nudibranchs the other day and they exuded a beautiful rich purple ink. The nudibranchs themselves were quite plain by nudibranch standards, mottled grey.

    Would you believe it.
    There is a sea slug forum.
    It's a sea slug slugfest.

    Here's Marianina Rosea. Lovely gal. Note the orange eyelashes.

    so nudis swim up to the surface and eat them?
    How do bluebottles make babies? Do the babies swim underwater like other jellies for a while or do they always float on the surface?
